2 ways to go about it.
First way:
1.) He just didn’t activate it . The reason could be anything. Arrogance, killed before activation, PIS….I don’t really need to explain why he didn’t activate if him and another SS member both heavily imply he first activated it later on and not during that moment
Second way:
2.) The conditions for its activation weren’t met as heavily implied by his dialogue. Aka he couldn’t activate it earlier because the circumstances wouldn’t qualify as a ‘Miracle’
I don’t mean to take up space with the images but I posted the links before and idk if you saw them cuz it doesn’t seem like you did
