Nutty S&L episode today. Great finale. With the
Official Confirmation that the show us entirely disconnected from Arrowverse, this means it can finally depend exclusively on its own feat rather than scaling to Supergirl, which has the standard inconsistency of CW writing.
About Tier 3/2 Ally. **** no.
She is merging the worlds, as in, the planets. The universe itself is not moving a single inch, she made a connection between the two universes through a wormhole.
This is Low Multiversal range Limited Dimensional Travel, at best.
She is shown pulling in the planets, but it's very blatant the planets were not being physically moved, as in, their actual mass. When they "collided", they just meshed into each other, meaning Ally was likely pulling the dimensional walls together, again through the wormholes.
There is a feat there, it's just 100%
not Tier 3 stuff. (Also the very obvious anti-feat of her being overwhelmed by a insignificantly small portion of the sun, it debunks this notion. She couldn't exert Tier 3 levels of energy if "less than Tier 4" shit is too overwhelming to her).
