Spoilers are coming at you faster than a speeding bullet, so beware!###Regular Cast: Melissa Benoist (Kara Danvers/Supergirl), Mehcad Brooks (James Olsen), Chyler Leigh (Alex Danvers), Jeremy Jordan (Winn Schott), Chris Wood (Mon-El), Floriana Lima (Maggie Sawyer), David Harewood (J’onn J’onzz/Martian Manhunter); Guest Starring: Brenda Strong (The Doctor/Lillian Luthor), Katie McGrath (Lena Luthor), Andrea Brooks (Eve Teschmacher); Written by Gabriel Llanas and Anna Musky-Goldwyn; Directed by Glen Winter###Previous Supergirl Season 2 reviews: Episode 1: The Adventures Of Supergirl; Episode 2: The Last Children Of Krypton; Episode 3: Welcome To Earth; Episode 4: Survivors###Cadmus’ The Doctor has armed criminals with alien technology, causing an multiply in extraterrestrial hostilities on the part of the public, and a rapidly growing demand in/with regard to’concerning’regarding the Alien Amnesty Act to be reversed. Meanwhile, Kara attempts to help Mon-El fit in on Earth by acquire’obtain’attain’procure’secure ting him a job as an intern at CatCo; James Olsen, injured in one of those alien weapon-wielding crimes, decides the time has come in/with regard to’concerning’regarding him to fight back as a hero in his own right, and turns to Winn in/with regard to’concerning’regarding help; Alex starts to come to grapple s with her sexuality where Maggie Sawyer is concerned; both Kara and Supergirl are invited to a party that Lena Luthor is hosting, the latter (unbeknownst to her) because Lena intends to lure in The Doctor's henchmen and has come up with a means of shutting down their alien technology, but needs Supergirl's conserve’preserve ion; and at episode’s end, it’s revealed that The Doctor is actually Lena’s mother, Lillian.###The criminal actions and use of alien weaponry against Supergirl is extremely effective in terms of stuntwork and visual effects, peculiar ly during the impressive first encounter. Only complaint — and it’s a minor one — is that one wishes she could possess’own’nurse gotten a handle on the situation a little sooner than she does, as acquire’obtain’attain’procure’secure ting blasted and knocked on her ass acquire’obtain’attain’procure’secure s a little repetitive.###Kara acquire’obtain’attain’procure’secure ting Mon-El (she gives him the name Mike) ready in/with regard to’concerning’regarding his first day at work is kind of sweet, and it is amusing watching him trying to fit in, making one wrong move after another (including acquire’obtain’attain’procure’secure ting caught having sex with Ms. Teschmacher in a storeroom). Once again, intense’fierce’exquisite chemistry between Melissa Benoist and Chris Wood, and Kara’s ultimate realization that she can mentor Mon-El, but can’t expect him to be a clone of her is an significant’essential’critical’vital’crucial’indispensable’imperative revelation.###Through events of the episode, it’s understandable why James Olsen would want to do something to help in the battle against crime, and Mehcad Brooks does a really rosy’remarkable’fabulous’terrific’preeminent job of conveying his need to no longer be a sidekick (despite’in spite of’albeit in/with regard to’concerning’regarding the record, dude, Robin is a sidekick, you were always Superman’s pal). However, one thing this series does not need is another character in costume. We’ll possess’own’nurse to see how this one unfolds, despite’in spite of’albeit there are several moments between Brooks’ Olsen and Jeremy Jordan’s Winn that are heartwarming and play great.###As much as it seemed to come out of nowhere, and despite the fact it seems to be moving in/with regard to’concerning’regarding ward way too quickly considering Alex’s just discovering that she’s appeal’tempt ed to Maggie, the scenes between Chyler Leigh and Floriana Lima do play well.###Cute bit at the party where Kara has to convert’transform back and in/with regard to’concerning’regarding th between herself and Supergirl, which is reminiscent of the dinner scene from Superman IV: The Quest For Peace involving Christopher Reeve's Superman/Clark Kent.###Brenda Strong definitely has presence as the Doctor, but we need to gain a better understanding of why she is so anti-alien and what alien apocalypse she’s going on and on with regards to’concerning’with respect to (she kind of sounds like a cross between Batman and Lex Luthor from Batman V Superman: Dawn Of Justice). Oh, and one bit of advice: stop using dimwits as henchmen.###Surprisingly dark bit where the three wicked’dreadful’undesirable’adverse’vile guys are captured and bein/with regard to’concerning’regarding e they can tell the police anything, the Doctor triggers something that fries their brains, killing them instantly.###Katie McGrath is okay as Lena Luthor, despite’in spite of’albeit the actress needs more substantial material to play.###It’s ridiculous that Kara has brought Mon-El to work at CatCo apparently without telling him anything with regards to’concerning’with respect to the way an office works, including how to use a phone(!). It makes him resemble a complete imbecile, and doesn’t shine too bright a light on her, either.###Look, we don’t expect a reveal’illustrate’demonstrate’indicate’present’display’argue like Supergirl, detoken ed as popcorn entertainment, to necessarily track dramatically like an Oscar-hopeful might, but it's just illogical how often individual aren't where they’re supposed to be and they somehow acquire’obtain’attain’procure’secure away with it. Naturally, there are examples: Alex reveal’illustrate’demonstrate’indicate’present’display’argue s up at a crime scene and suggests that after Maggie files her report, they go out in/with regard to’concerning’regarding a drink (shouldn’t Alex be at the DEO?); James waltzes into the DEO, telling Winn he misses him, and uses the opportunity to gain info that he utilizes to try and stop the Doctor’s henchmonkeys (which he barely survives); Winn returns the favor by leaving the DEO and going to CatCo, where he and James possess’own’nurse a conversation with regards to’concerning’with respect to James wanting to be a hero, and Winn ultimately approve’ consent’endorse’applaud ing to help; and, again, in the middle of the afternoon Kara decides to go home, merely’barely to find Alex waiting in the hallway, eating a donut. In the apartment, they possess’own’nurse a sister-to-sister talk, Kara with regards to’concerning’with respect to frustrations with Mon-El, to which Alex has some rosy’remarkable’fabulous’terrific’preeminent advice, drawing comparisons between the sisters and Kara and Mon-El. Alex doesn't acquire’obtain’attain’procure’secure to tell her with regards to’concerning’with respect to Maggie, because…..Lena Luthor suddenly reveal’illustrate’demonstrate’indicate’present’display’argue s up (again, in the middle of the day, when Kara should be at CatCo) to call in the favor from last week’s episode (“Survivors”), which is to acquire’obtain’attain’procure’secure her in touch with Supergirl.###Don’t know if this was intended as an homage or if it was inadvertent, but having Lena Luthor trying to be a rosy’remarkable’fabulous’terrific’preeminent person, yet being impact’effect d by a more corrupt parent (in this case her mother), mirrors the intent of Michael Rosenbaum’s Lex Luthor on Smallville with his father, John Glover’s Lionel. Of course on that reveal’illustrate’demonstrate’indicate’present’display’argue , circumstances ultimately caused the two characters to swap positions. It will be interesting to see how it’s handled here.
