[Iwaizumi bristles at each and every one of Kaiba’s words. It’s enraging that he’s trying to stick his nose into Iwa’s business and ruin his good time - some of the only activity that’s been able to bring him any peace in this place - but it’s even more infuriating that he’s trying to pull his bullshit wool over Ann’s eyes. If it weren’t for the fact that he trusts Ann’s perception enough to realize she probably knows Kaiba’s flaws better than anyone, he probably would say more about it - out of respect for her, he doesn’t.]

I told him if he wanted to play he could learn from someone else. [He says with his eyes on Kaiba. Eventually, he turns them back to Ann.] I know you like this guy, but I don’t, and I’m not trying to tangle myself up in more bullshit forcing something that can’t be forced.

[As for who will be practicing with who...] The rest of the team is heading home. I’ll be back here in an hour or two, so meet me then if you want to practice, okay?

[A simple invitation, and said without the same venom he’d been using when addressing Kaiba. He’s talking to Ann - his friend - right now, and so the tone is gentle, inviting. If Kaiba wants to take offense to that, let him (and if Iwa takes enjoyment in that offense, well, it can’t be helped).]
