Gwen shouldn't be thanking Hunter period. Not considering his role in her problems. And there was a solid chance Darius wouldn't even agree to this. He had to try though.
She was much more cheerful after that. She told him about how she filmed her first attempt at a longer video earlier and still had to edit and post it once she figured out how to speed it up.
That was the perfect segue for him to get her usernames. It was the same across YouTube, TikTok, and Instagram: gwendraws. Straightforward and to the point. Even if he couldn't talk Darius into doing him a favor, he should at least be able to get her some more exposure and ad revenue.
They enjoyed a perfectly pleasant dinner aside from his crippling guilt and had plans to meet up again two days later so he could feed her again and try to feel less terrible. He didn't tell her that part though. She thought they were meeting again for the heck of it.
