Evan had posted an ad which read:

Looking for a tattoo artist

Male/female/non-binary/alien idc

Rent to be split in 2

I'm a piercer, need a partner

More info: +44 20 7123 4567

and he'd finally got a response... Barty would be moving in today. He'd talked with him over messages and he seemed friendly enough and he was glad to be able to have a tattoo artist and someone to share the rent with.

Right now, Evan was just sat in the studio, humming along to some music, as he waited for this "Barty" guy to finally show up...
