He blinks, realizing the other had stopped him. His arm grabbed and all. He stopped, looking back with a confused look on his face for a moment, which softens a moment later. He gave Diego a soft sad smile, reaching a hand up to pat the hand on his arm.

"I know." He said it simply, but decided it was too simple. "I've been around Klaus all this time. I was able to connect to him while I was gone. I... didn't get to see much of any of you while he was away from it all, but I'm very sure I didn't just get dropped out of the family. Forgotten or anything. Promise. I never thought you of all would forget me." He said, trying to give him a reassuring smile.

He knows how important the family is to Diego. Or... he thinks he knows. His good protective brother. He saw how Diego was with Klaus, and that meant a lot. Tht even if Diego thought Klaus was a fuck up, he was still there for him. It made it stick in his mind, that Diego wouldn't have forgotten Ben so easy either, if he could continue to protect Klaus when he could.
