[Well, at least he's not actually sick, which is something - exhaustion is much easier to deal with. With that in mind, Ren pulls him up with a motion that's perhaps a little easier than the time he would've had with it back home. He was never exactly weak, considering he was strong enough already a few years ago to pull someone Tetsu's size away from the edge of a rooftop, but he's been working with dragons for the last few months, and something had to give in terms of his ability to handle them physically.

Once Aichi is up and resting on his weight a bit, Ren lets go of the hand further away from him so Aichi can stand by his side more evenly, and instead places it on his far shoulder as a bit of a bracing grip as he starts walking again. And then starts pouting rather petulantly.] You should be...it's not like we don't have enough to worry about already, you know? If you hide things until they get worse than it just ends up worrying people more.

[Clearly whining about it is going to make him feel better.]
