Des*iel has nothing to do with bisexual, doesn't it? It's, Idk, other species love? I saw some destipeople insisted like "Cas occupied his vessel now" many times but it doesn't matter imo. It's still Jimmy's body and more important, Dean thinks so too. He actually said "you are wearing her old man’s meat suit" in 10x09. Btw Cas was so worried about Claire in S10. Do you think he still care about her? I bet he almost forgot her, again.
Yes, my dear anon, as far as Dean is concerned, THAT is still Jimmy’s body.
**snorts** Well since he is now in Heaven, I doubt she even crosses his mind, which is probably why he isn’t in her episode this season. Out of sight, out of mind.
Another long gone character taken out of storage to give a current stale character a storyline, only to hang around long past the point of usefulness.
