[If Cilan had been able to hear that "weak" comment being made, he'd argue against it, because Red is not weak in any sense of the word in Cilan's opinion.

However, there's a bit of a pause before he carefully moves a hand from Red's shoulder to the other one so that his arm goes around Red, offering a sort of one-armed hug. He can't say that "it's okay" because, well, it's really not. But...]

It's going to be okay. [It's going to be okay, someday. This will pass.] I'm... sorry, for not being able to change what has already happened, but we're here to help in any way we can. And I'm sure your Pokemon feel the same way as well, so... you don't have to deal with this alone, okay?

[We should probably try saying more, something that will keep the carpet from continuing to burn (or his own dark wisps of anger and grief from forming clouds), but... to be fair, trying to help someone cope with their own death after having come back to life from it isn't exactly something that was taught and added to his data as a Pokemon Connoisseur. The best he can do is just try to be there for his friend like this.]
