okay so back in eaaaaarly Act 6 we got this lil tidbit from Aradia

ARADIA: no need to be so modest dave
ARADIA: tactically speaking a knight of time and a seer of light is a nearly unbeatable combination 

and it didn’t really seem justified to me yet, considering our view of Dave as a combat entity was “he fast, and sometimes time clones” and Rose’s abilities as a fully realized Seer of Light weren’t really apparent. But in light of Collide, my god, it makes perfect sense

When Dave combined his powers with Terezi’s abilities as a (non-godtier) Seer of Mind, the two of them became able to sort through alternate timelines based on the decisions the fighters could have made, then consolidate those alternate selves into one favorable reality. Timeline selection, in short, based on decision.

ARADIA: the seer class knows her aspect comprehensively
ARADIA: as a knower of all fortune she can see the circuitous path that will lead to the most favorable outcome for everyone

Rose’s powers are those of strategy. She doesn’t see possibility based on decision. She sees the most advantageous path, period. Instead of a circumspect view, Rose comprehensively knows what things ought to look like.

Combined with Dave’s powers, we can pretty comfortably speculate that Dave and Rose together could actually shift timelines based on what was already fated to happen, in effect moving from a doomed version of a battle to the alpha one with one fraymotif and combining the selves from the doomed and fated continuities. Dave and Rose’s powers in conjunction should technically be impossible to beat, as they can just change timelines to one in which they win.

Jesus, but my babies are monsters.
