In Spy X Family Season 3 Episode 12, things got real. The whole episode was heavy with high stakes for espionage and drama. Twilight was in the middle of all of it, having a ton of close calls. Plus, we really got to see Twilight's limits tested.But, as crazy as all these little moments were, there was one moment that stood out beyond everything else: Fiona's punch. But it also did quite a bit of damage to Fiona’s own arm, breaking it in multiple places, all to protect Twilight. That just shows how loyal, how strong Fiona really is, and how crazy this show has gotten in Spy X Family Season 3 Episode 12.Twilight's Toughest Battle YetTwilight in disguise gets shot by Yuri (Image Source: Wit Studio and CloverWorks)In Spy X Family Season 3 Episode 12, Twilight had to face extreme danger during this mission from beginning to end! The first fight did not go well for Twilight as he was up against Yuri, disguised as an SSS agent.Even though Twilight has superior fighting skills, he had trouble keeping Yuri down because the Briar family has some kind of superhuman toughness. Twilight hit him with a couple of nasty blows - a whip with his belt buckle to the throat and a pipe across the head- and Yuri just kept getting up like a freaking zombie.The hesitation to kill Yor's brother proved costly for Twilight. Because he chose to show mercy, instead of killing Yor’s brother, his arms were injured by a shot. As a result, Twilight cannot defend himself because his injuries from battle have weakened him. Since he is no longer able to fight back from pain, Wheeler, the rogue WISE agent, easily defeated Twilight, who was previously invincible.Fiona's Rage Mode Activated in Spy X Family Season 3 Episode 12Fiona's one punch sends Wheeler flying (Image Source: Wit Studio and CloverWorks)Fiona showed up, and things flipped upside down at the scene. Spy X Family Season 3 Episode 12 showed Nightfall in a way fans of the manga have been waiting to see, with her stoic expression shattering like glass when she saw Twilight in danger.Watching Fiona turn into "berserker mode" was really freaky. She looked insane, just staring at who was trying to kill Senpai, but the animator nailed her rage with the way her breathing sounded like a boiling kettle. Wheeler totally failed at realizing how emotionally attached Fiona was to Twilight.Fiona lifted all limits off of herself so she could hit her hardest. The sound effects were disgusting sounds of Fiona's arms breaking at the shoulders, elbows, and wrists at the same time.Wheeler couldn't see this coming; he figured it out too late that Fiona's punch would break his guard. Her hit broke Wheeler's arm and jaw and sent him down on the floor. This scene reminded many fans of Deku's self-destructive punches from My Hero Academia. In the end, Fiona's love was stronger than Wheeler's "trust no one" philosophy.Winston Wheeler: A Mirror of TwilightWinston Wheeler, as seen in the series (Image Source: Wit Studio and CloverWorks)Wheeler was another bad guy in Spy X Family Season 3 Episode 12, and added a really interesting depth to the story. He was the same type of spy as Twilight, and together they were really good at knowing where an enemy was, even if they were hiding.Wheeler believes that being strong is having no emotional connection with anyone in your work. His monologue is in direct contrast with Twilight's growing emotional attachment to his fake family. The difference in their beliefs provided for much more than just physical fighting. Wheeler represented what Twilight could have become if he hadn’t had the Forgers.Chloe's Growing RoleA lighter moment in Spy X Family Season 3 Episode 12 featured Chloe tending to the unconscious Yuri. The anime gave her a little extra blush than what's shown in the manga, and when Chloe got frustrated with Yuri's sister being so obsessed with him, it gave a nice laugh during some serious moments.There was an indication that Yuri may have some romantic feelings for someone else besides his infatuation with Yor. And how Chloe was around during this also shows a little bit of the SSS doing some normal things. Her sensible response to Yuri's delusions about going back to help him was an example of how Yuri needs that type of thinking for himself.Spy X Family Season 3 Episode 12 totally builds up anticipation for the final episode next week! Fiona seriously messed Wheeler up, and we don't really know what will happen to him now. Getting Wheeler off the streets would be a big win for the WISE organization.
