Hmm. There have been two times where they fused.

First, in Alone Together, Lars, Sadie, and Kevin fall for Stevonnie, as I said. None of those characters, including the gems and Sour Onion, use pronouns to address Stevonnie.

Second, in We Need To Talk, Greg says, "You guys can fuse now?!" This suggests that people who know about what Stevonnie is might use "they" when talking to other people. Citizens of Beach City and other places might use "her" or "him" due to Stevonnie looking unisex.

Maybe the writers don't want to explain.
