Jay and Miles are just getting to the original Onslaught now after delaying as long as they possibly could! I think I am glad I'm not reading it in the comics.

But is it really a major comics enemyship if some kind of child of theirs doesn't show up in some storyline at some point?

"They are always each other's Most Important Person, but not always in the same way" is probably my most enduring OTP dynamic.
