[The possibility of Kohan getting worse only makes Ion frown -- in truth, he was more worried about Kohan falling asleep and then waking up alone and being too disorientated to know where he is.]

I think sleep would be good for you right now. [He takes a moment to press the back of his hand against Kohan's forehead, checking for a fever, before pulling back and standing.] I'll be back in a little while, all right? Please, try to get some rest.

[And unless Kohan has anything to say that might convince Ion to stay, he's gonna go in search of first aid things, and maybe some water and light snacks in case Kohan or Ion because he did just wake up and all gets hungry later.]
