No one is denying that. The issue isn’t that they kept the dragon. The issue is WHY they kept it, which was deliberately to spite the original owner - this isn’t even speculation, that’s straight up what Nobody999 said.

It can be assumed they wanted to spite the owner because they got called out by them for being transphobic. (Nobody999 never intended to keep the dragon just because they like it - and people don’t typically change traveling dragons older lore, much less just the pronouns.)
