"Of course I want to go home." He's been huddling in a cave having a breakdown because he's so happy in Wonderland, obviously. "She does too despite her... tendency to look on the bright side of things." And despite her fears about the apocalypse. She might not be as eager to go home as Dipper is for that reason, but she doesn't really love Wonderland. It's brought them too much pain.

"But yeah, having her here, and my great uncles, and... Soos. It makes it better." But mostly Mabel. If she wasn't here, he wouldn't be able to handle Wonderland at all.
