If anyone is going to die in 5.5 my money would be on Arenvald for the following reasons:
- Minor enough not to cause outcry, but major enough for people to know who he is.
- A close tie with both Alphinaud and Fordola. We know Alphinaud is going to be working up to a big "character moment" as he's going to change class, so this would potentially spur him forward.
- He doesn't appear in the trailer at all, but we do hear him. This is... strange, and a little suspicious.
- They said they had trouble "cutting around the spoilers" for MSQ in this trailer, and his absence feels like they want his appearance to be a surprise.
- We see Alphinaud frustrated in the trailer at not being able to save someone (I don't think this is him, but it's definitely a theme), and he looks sad or apologetic toward an angry Fordola in the scene where she pushes him over. Maybe reaching a bit, but this scene would make perfect sense after his death/something happening to him.
Like I've said before, I personally am not the biggest fan of character death but in this case I could actually see it making sense to progress the plot (Alphinaud's character development, and also development for Fordola, who could possibly join us in Endwalker).
