Hey, just something silly here, but I actually prefer Streber surviving, instead of Bob just simply killing him...
...
Because having him survive is more depressing...
Think about it, his arm was literally ripped off, that's a whole part of his body just GONE, he's going to have to re-learn how to do things like writing, getting dressed in the morning, brushing his teeth, etc, stuff that was originally easy for him...
And even in the best case scenario where he gets a prosthetic arm, he's still going to have extreme PTSD afterwards, getting your arm eaten off would fuck with ANYONE, he's gonna experience things like flashbacks, nightmares, feeling very anxious and he may even have difficulty sleeping...
So, yeah...I like the idea of him surviving more...
