So I know that Dave was basically Hussie's internet persona at first, but how far do you think that goes? Like is he still basing Dave off himself all the way up until the end? Is Dirk based off him too? When I found out Dave was gay I thought that was Hussie's way of coming out until I remembered that Dave is a character and not actually Hussie

He separated himself from Dave after a point I’d say, however you could say Dave coming out as Bi could be Hussie reflecting on his own sexuality, or just understanding more modern LGBT issues and showing his support in a more personal way. Also I believe he mentioned Dirk being a little bit like him too? But not that much. Just the Strider vibe in general.
