All of this! I have so many feelings about Jeff and Delenn. Mostly I just want them to interact forever. But you can clearly see how both of them have such complicated feelings about the other side. I don't think Delenn is lying when she says she's his friend, and I do think he considers her one. At the same time, of course, it's just been shoved in his face that she's A Minbari, particularly one of the ones who fucked him up during the war. And how much of Delenn's worry for him is because he's her friend Jeff, and how much because of the Valen connection? Layers up on layers.
