[There is a very large chance that Chipp had been in the middle of something, be it the games or just enjoying the food and drinks that the teahouse has to offer...
But when Nenonen says they need him, they need him. So whatever it is gets dropped as he lets himself get tugged along to meet this "nice red person" that Nen's talking about.

You really are just gonna yank me 'round and show me off to everyone, huh...

[Then, to Karlach:]

Nice to meetcha. Nenett ain't say anything weird 'bout me, right?
