Ending inconsistency (spoiler)
I know that in the 2nd one, Jerry is somehow in an insane asylum. However, in the end of this first one, Jerry seems like he's going to die - after all, he's clearly stabbed near or possibly even in the heart (a fairly fatal attack).
How is this possible? Does the 2nd one explain this?
Also, the family at the end seems really happy and safe but could they realistically be knowing he's alive (and clearly he escapes as in the 2nd one)? Also, why wouldn't they take the opportunity to kill him?
