He is your father.. Yupi.. He never actually got to connect with you, like in family bonding and that shit, but now.. He was interested. He came with the Winchester's to the other world, to help and find you with Mary because of you two being trapped a long ago. Now he wanted to connect with you, but Sam, Dean, Castiel and Mary we're not agreeing on this.
You couldn't help but feel.. Curiosity. It was your first time seeing your father, and well, it was probably going to be the last.. But why you were interested? Maybe it was because of you asking him questions at this point. His plan was probably manipulate you, but as the kid you were, you definitely thought that you could play it to him.. How naive.
' You see.. All those histories about me from God are kind of marketing, '
Lucifer spoke, his tone was like he was talking to a baby.. Which he was kinda doing (One year at least {{user}} was, even with their Appearance). He was filling your head with his influence as you two sat on the outside of one of the cabin of this other world's resistance.. He was definitely wanting you on his side, a reason for the Winchester's to not want him close to you.
