Me, [ he says lightly. ] I think Dipper's pretty cool. As for Mosley-san... I'd say it's the first one.

[ He frowns a little in concern. ]

I don't think he'd leave us voluntarily. Or his job, for that matter. He was pretty dedicated to it. To be honest... I have reservations about Mosley-san, but I'm worried for him.

[ Yu talks to Mabel like he'd talk to the normal Mabel. He sees no need to call her out on her weird behavior, which would likely only alienate her while she has no control over what's happening. It's funny... even like this, she's not really so bad. ]
