Response: Let her understand she was just misunderstanding, easy, right?
Well, at least I think so, because it worked with Shadow (well, kind of) and with Silver in the past.

The idea though would work because Surge was programmed to destroy Sonic, without having memories of her past.

Now, I know perfectly well that this scenario is hardly to really happen, but hey, that's why what-ifs exist, right?
