Fullmetal Alchemist: Brotherhood (2009)
After ROTS, Obi-Wan gets really sick. Knowing that he won't survive, and also can't be on his own, Obi-Wan heads to some mid rim planet and checks himself into a hospital. He goes under his own name because he's already dying, and Vader shows up - only to be confronted by a delirious Obi-Wan who thinks he is a hallucination, and apologizes and says he loves him, and says he knew about Padme but just wanted Anakin to be happy...Vader decides to take Obi-Wan with him/save him. Vaderwan please!
