Byleth has shared a body before. This is new though, and he wonders briefly, after realizing this is not his own, if this is how Sothis felt? He's aware someone is talking to him. He feels his ear twitch and his head turn. He feels a fury in his heart. A deep, smoldering resentment not his own.

There is a man prattling on, and inherently, he understands the context somehow. Of course. The damned Temple Knights. He seems to have tentative control of this body.

Looking down, he realizes.

Ah. How could he mistake this... view. He is in Obsidian's body somehow? How queer. He accepts it far more easily than most might expect. Though there is some dull surprise and confusion, this is hardly the strangest thing to happen to him. He will see how this shakes out.
