Soo....I win? Yes. I win. Or at least get a point. ONTO KIDDO CONNECTIONS. XD
Katsurou: First of all, love this cat to bits. Seriously, I do he's kinda awesome. XD And secondly, that becomes even more exciting because J.D. would know him through his work through the Sentries, esp. because it's only been in the last little while that he's stepped back into the role he's in now. So yay! I...really am not seeing a lot of problems between these two. Because...J.D., and Katsuro's first post made him want to eat a lot of cookies too. Like...a lot.
Logan: Again, I think J.D. would know Logan through the Sentries. And you know Mr. Rhodes here is the poster child for not talking to anyone so clearly, they'd never have a reason to talk. =p Seriously, I know J.D. would strike up convos with Logan, and back off if he got the sense that Logan needed some space, esp. a little more recently. :)
Sam: Clearly has no idea who Sam is at all, because clearly Owen and J.D. aren't bromantically involved or anything like that. And clearly they won't have any interactions between them because of that, or because that they're both Sentries, and now that J.D. is trying to be Mr. "Don't worry I'll keep any turf wars from happening between us and the other us (military)" or something along those lines. haha.
Miranda: Nope. Got nothing for you here. Nope. Not at all. None of the things. And he's totally not like "So...when do I get to see her in the pretty dress and she's going to force me into my dress uniform?" Nope. Not at all. =p
Magni: Sentries! J.D. would not encourage the "Shakespeare in the park" talk. Nope. He would not also try and learn it as well. He's probably tried to convince Magni that they do in fact need to become more "bad ass" and have a lion mascot. I'm sorry. Out of all the people in the Sentries he's trying to convince...I don't...even...yup.
