[Ah, yes. The first time spotting how pokeballs work. Dimitri has already seen Byleth experience this before, he's fairly certain, but somehow it's still just as endearing for the second time. Dimitri smiles a bit.]

They did indeed go inside. From what I have inquired of my own companions, whatever they experience within those balls, it is quite comfortable and reassuring. I cannot tell you how they fit, unfortunately.

[He is but a simple jock, and Byleth should know this. Maybe Annette would have a theory. Or any of the people theorizing about Pokemon just being made of pure energy or whatever.]

[In the meanwhile, he rests one hand along Elshot's feathery neck and gently strokes him.]

You have some time to consider the proper name for them. That creature in particular is called a Shinx. When we get you in warmer clothes, we can discuss more... Ah, that reminds me. [He reaches up for some of the bags he has attached to Elshot, and pulls out a warm sweater.] Here you go, Professor. It is mine, but hopefully it is not lacking in any way... We can make a stop in Cherrygrove City, which is a short distance from here, to find you other clothes, before making our way to Goldenrod. There will be some traveling involved, but... We should be able to do well.

[Elshot knows Johto quite well, now, and so he knows the fastest ways to get back to Olivine.]
