I've never even thought that people might find this strange, anon! I do something similar, but I play the character from a different universe. And it's mostly ship-teasing, not actual ships (they've never gotten together/have yet to get together when I play them.)

I just get excited, I guess! No one ever plays these characters, so I like tagging them. It just so happens that it ends up shippy, and I get really happy when it ends up that way!
