After flowey says please don't kill me, Chara would appear somehow and do her monologue.

You would then be presented with FIGHT or SPARE, like in Asgore's fight. FIGHTing flowey would prompt the great partner monologue, while SPARing flowey would cause chara to kill flowey herself, say "Since when were you the one in control", and jumpscare the player.
