12x07 | Rock Never Dies | Lucifer
“Dear old dad, he finally apologized for abandoning me. And what’s the very next thing he does?”
Just wanted to point out at these words in particular. Even when what Lucifer says could also mean that God ditched Sam and Dean too, I think Lucifer was referring to the boys ditching him as well. Lucifer first says that he isn’t interested in God’s opinion because he has left him behind (again), and then points at Sam and Dean and accuses them of the exact same thing. They were a ’team’ at the end of s11 after all. Lucifer sums everything up basically by saying he can’t care less for the opinions from the ones who have abandonned him.
