His perfect scenario was Black sperm divide to the max and kill all humans, the fact that he fused destroys that plan so I fail to understanding your argument.
Him getting on his good side isn’t an argument for strength, all this proves is that he has another plan, and the same argument can be made for GS. He states he needs to sneak HE in order to kill him, yet, despite wanting to kill him, he still doesn’t do it head up after fusing into GS. Does this mean he still needs to sneak him to win?
And what does durability have to do with it, Homeless could be getting on his good side because of his overwhelming speed.
