@Paperchampion23 at this point I believe Kizaru switching is inevitable. I don't see what else he could logically do in the remaining 6-7 minutes.
Holding the Gorosei off for the crew to escape is the only thing that makes sense rn.
Something has to come out of this being conflicted plot and going back to the Navy like nothing happened doesn't make sense.
Luffy definitely isn't getting any 1v1 against a Gorosei this arc.
