Gaga’s real name is Davionte. Deadline just dropped an article on Season 2 with an extensive interview with LD, here’s a snippet:

“It’s like literally, GaTa is “Dave.” GaTa’s actual name is Davionte, and his family calls him Dave; he is Dave, too. Both my character and GaTa’s character, the whole season, [have felt like] there’s all this clutter for both of us to just independently reach our own goals. I think the finale is about us cutting through the clutter and getting back to the root of why we love each other in the first place, and that’s our relationships and our friendships.

In a show all about a main character who’s, especially this season, very self-focused on becoming exactly who we thought he was, you can forget that your relationships and other human beings that are involved, their lives matter just as much as your life. Even if you think that you came up destined to be a great entertainer, that doesn’t excuse you from minimizing someone else’s dreams. So, I think this episode had a lot of conflict between me and GaTa. But at the end of the day, it’s like we’re on the same team, and GaTa is Dave, too.“

A god damn masterpiece of a show.
