Honestly I feel like most of the issues with Roxy comes from how his character in Meat gets sidelined (frankly this applies to Meat as a whole post-epilogues), and hopefully we get to see him develop more as he discovers himself. Same with Candy Roxy and whatever genderfuckery she's got going on, lol. Though, I think that it does need to be said that despite falling by the wayside in terms of the actual plot, Roxy in the Epilogues is the primary character though which the narrative is exploring gender, in both timelines they give big explainers or dialogues on processing identity. It's a little clumsy and blunt but honestly I think showing this approach to gender is an important role for what the Epilogues themselves are trying to do. Their conversation with Dave, in aprticular, did a lot to affect my own gender and identity feelings - they're not something fixed and immutable but something that can change depending on context (meat vs candy roxy) and self-evaluation (dave's shifting sexuality); gender identity can be something that is artificial and constructed while still being an authentic expression of self. It's a very nuanced perspective that I haven't seen very often. The follow-up may leave something to be desired but I do think the foundation was good, and it's just hard for me to judge too harshly based on the scraps of transmasc Roxy we've received.
