A relationship that doesn’t get looked at a whole lot. Dick and Babs will always be the Batfamily’s core, and Jason has always been the black sheep, even more so than Huntress. But it stands to reason that Barbara and Jason were friends at some point during his time as Robin. With everything that’s happened to both of them, I think both of them have realized what family is supposed to mean, and in that one moment, Barbara looked past the Red Hood, and saw Jason again.
Batman Eternal is a testament everyone to what good writers can do with great characters. Hope to see more.
