I reallyyyyy hope that's the case
I mean, if you think about it, doctor is a staple part of this series just like blanca.
It makes sense that, if the vital monitor says he's dead, he somehow got it knocked out of him (from his wounds, thats a possibility) or he took it out of him. Like, it doesn't make sense to kill him off unless he's either:
1. by some miracle he comes back alive
2. He is back to being alive, but as a mutant.
Or some other possibility i havent seen yet.
