Briefly. Anakin trusts Cassian's memory won't fail him. He watches the other man's mind working, recalling details, remembering conversations and the edges of his lips quirk upwards.

"That is easily remedied." he pauses perhaps for effect, "I am Anakin Skywalker."

If Cassian is from his future - which seems likely - he will know him by another name. However he has encountered those - even from the future - who recognize the name he gives.

"Care to return the favor?"
