Obi-Wan smiles and ducks down so he can kiss Klaus before he says, "I love you. Every bit of you, no matter your form."

While he knows Klaus knows this, trusts he believes it, Obi-Wan knows what it is to regret things unsaid. He won't do it again. While it may be easier for him to let go of regret than some, he still doesn't want that experience every again. Even now, there are days when he regrets all the things he never said to Cody, to Ahsoka, to Kit or Shaak Ti.

He has a chance not to be that version of himself again and he's going to take it, starting right here.
