Honestly, Roger wasn't surprised when Mark accepted his offer. Sure, it would be nice to have his own place, but really? Roger probably did need Mark around to monitor him. He was pretty good about the AZT but there were days when he forgot. Which really wasn't smart. But he was trying, so that had to count for something. Regular doctor visits and the like. But when he got too caught up with his music, medicine mostly feel to the wayside. It wasn't intentional, it was just... Roger. So having Mark around to remind him would be good, even if it were only temporary.
Ah yes, the tattoo.
"Right. Jewish customs or something." Roger never really paid much attention to religion, but he recalled his attempt to get Mark drunk to get a tattoo and the blond man freaking out about how it went against Jewish culture and burial or some shit like that. Whatever, Mark adhered to his Judaism, so Roger would try to respect that. You know, when he wasn't mocking him about his little... documentary about certain issues he had on high holy days.
"Thankfully I've never been possessed so I don't really know what happens. But from my understanding they make you do things you wouldn't do, hurt people. The amulet," Pulling his own off, Roger showed it to Mark, "keeps them away apparently. I forget if it's demons that have the white or black eyes, or those possessed.... But yeah. Say 'christo' at a demon and that bugs them."
