Because of the UP barring us from taking on any new members from within the UP we now have strangers -- that would be you -- volunteering to endanger themselves when the primary focus should be returning them home.

Also, we have to take time out of our already immensely busy schedules to train you. While simultaneously preventing the total breakdown of UP society, trying to find out what happened to our friends who have been missing for a year, and trying to engineer a way to get you home.

You're yet another complication in an already complicated situation. You shouldn't be happy to see us, either.

Since seeing us means you're not home. Where you should be.

[At least his annoyance seems heavily rooted in wanting them to safely be in their home universes? Kind of?]
