I dont think Master Chief got it? (Spoiler)

Hey guys, just wondering if any of you thought in halo 4 that master chief thought WTF? in cortana death scene. I believe that when she was telling master to " hold them off chief" and in the background debris is falling and that. I swaer like beneath his helmet he though WTF is with this -Yoink-

I bet he was thinking, “Damn, I should of hit that when I had the chance.”

He’s probably thinking that if he would have never awoken the didact none of this would have ever happened.
