I think zoro and sanjo will beat them up. Meanwhile Imu is getting jumped by Loki and goofy and will get his ass handed to him. So in a last ditch effort, Imu will take back his power from Sommers and Killingham, and use that burst of energy to teleport outta elfab.
Killing sommers and Killingham, while also not making imu any weaker for their deaths, since imu just reabsorbs the power he lent them.
We already saw how imu killing saturn did not have any effect on imu. This way, two HK will die and inu won't be any weaker, and we might get two new hk for endgame too.
