[mick can see the cogs turning in her head even if she doesn't say anything more than a gruff 'no' to his question about oliver. he knows she's considering the validity of his statement, meant to caution her because he understands that lack of impulse control very well himself and because he cares about her. and kara cares about oliver. so by the transitive, mick cares about oliver even if the guy rubs him the wrong way.

he's glad that she ultimately drops the angry boyfriend route in favor of fighting her own battles. she's certainly more than capable and has proven herself of that on more than one occasion already. a shake of his head and he continues.]

You're bulletproof. Would my fist have done anything other than hurt where it hit you? It wouldn't be the first time someone's shot at me. I may be big but I'm not that slow.

[more softly though, and maybe with a hint of mischief in his voice]

Just trust me. Your boyfriend will thank me too. I swear.
