>>2993174To be honest, I see the Orga/Mika relationship as sickly codependent: Mika surrenders his free will (which he obviously has) to Orga to do as he deems fit, and Orga willingly exploits Mika's unconditional trust to do questionable shit that he can't/won't do. I still think that he had him execute the First Group prisoners because at the time of truth his hand would've shaken and he could not afford to show any form of weakness as a leader. There's this idea that Orga has to die or betray Mika in order for him to grow up, but I don't see it happening - I think Orga has just as much growing up to do, and part of it involves not relying on Mika as much.
Now, the Kudelia thing. Mika is shown to be uncaring or hostile to anyone outside of his group, and a cool guy with those inside. He's closer to Orga, yes, but he feels for all the other Tekkadan kids: you could see him hurt and angry thinking of the ones that died during the raid. Kudelia was simply just a random girl at first to him, which is why he was cold and tactless towards her in the first two episodes. It's why he doesn't think twice about choking the life of Gaelio (outgroup) because he thought he hurt Cookie and Cracker (ingroup) But now that Kudelia is in the shit together with them and doing what she can to keep Tekkadan running, she's part of Mika's group now, which is why he's mellowed down and trying to keep her in high spirits. You could even see it in purely mercenary terms (as long as Kudelia is happy, we get money, if she is depressed and backs out of the job we're SOL) if you wish, but it makes sense that Mika is making approaches even if they're kind of awkward.
(From a shipping point of view I'd like Mika/Takaki but I know better. Kinkmeme anon, hurry up!)
