Gunther likes to sew, but he also knows what his priorities are. He needs time for his studies and Bets wants him to drop everything and sew complicated cosplay outfits for a romantic date she didn’t even consult him about. And they need to be ready in less than a week! It’s not much of a romantic gesture when someone plans it but you do all the grunt work to make it happen.
I’ve heard of people living on houseboats before. It’s like living in a camper, but in the water. I’m sure there’s more to it than that, but you get the idea. You don’t need to be rich to live in one, but it helps.
It’s admirable that she wanted to help a friend. It was incredibly dangerous and stupid to do so by letting her crash in the backroom of her parents business. So many things could have happened. She could have asked her parents if Tara could stay in her room for a few days while they figured something else out. The worst they could have done was say no. But Luann put Tara, herself, Bernice, and her family’s business in danger with her rash, irresponsible decision.
Note how amused Gunther looks and how surprised Bets looks.
