If Gamzee can never die, then he can never ascend?

I mean, Gamzee can die! As we saw in Game Over. It’s just that, if he dies, the Timeline is automatically deemed Doomed, so no matter what happens to him in the Alpha, he’ll come back. So an Ascension Death, a Death where he comes back and resurrects, would be technically plausible for him, since he’d just. Come back.
