He spends a week alternately crying and blowing things up. Every Earth day, loyally, he writes a letter to Boots. 

I'm trapped I can't get home I don't know what happened I don't know if it's this universe don't come get me but summon me out please I'm lonely.

He rips that one up, not that it'll interfere with Cam conjuring it.

Sorry for failing to communicate very well. I'm not in any danger. I'll try some safe experiments to figure out what happened. I'll write every day. 

I think I leapt twice. By trying to leap with magic while holding the prototype worldleaper. I tried jumping to the intermediary world, but I don't know anything about it and I shouldn't jump at random. I'm being safe. I miss you. I'm sorry. I didn't do it on purpose.

This is a big universe. I should go talk to people but I don't wanna. 

There's a Bell!

And a second after that there is an Epic next to the Bell holding a plastic scale model of the Bell's surroundings. (He is invisible and inaudible.)
