Davesprite didn't fuse with Dave when he went god tier because the Dave from the future timeline wasn't his dreamself, right?

Davesprite didn’t fuse with Dave because:

1- He’s from a Doomed Timeline.

2- He’s the Real Body, not the Dream Self, so even if Dave Ascended normally it’d have no bearing on Davesprite.

3- He Ascended in the Sacrificial Slab on the Moon rather than on the Quest Bed, to Ascend without a Spare Life.

So yeah.
