Gwen was slowly but surely getting over the trauma of what happened. It helped that she was both busy with work and with other plans.
Becca was now very pregnant and very bored so she ended up spending a lot of time with her. She had been watching a lot of nail art videos and wanted to know if Gwen could do anything like that.
She had never tried before but looked up various techniques and got herself some tools so she could do it. There was nothing wrong with adding some nail art videos to her channels. They were still technically art and a lot of people liked watching those, not just Becca.
Once her other friends found out about this, they wanted in on it too. Gwen did Joy's and Noelle's nails as well. She had to put fake ones on the former though because she kept her nails so short and it was hard to do anything with them.
