CthuluIsSpy said:[spoiler:087c04a341] I didn't miss the point. I know that all realities with Comstock are erased. However, if all realities with Comstock are erased throughout time, then there could be nothing to trigger their deletion. Remember that the Elizabeth we know is a product of Comstock's timeline. Hence a paradox [/spoiler:087c04a341]
[spoiler:087c04a341]The paradox is the point. In theory, quantumphysical interdimensional paradoxes like that "delete" themselves, kind of like an equal amount of matter and antimatter make eachother disappear. As the only choice that now does not create a paradox is Booker refusing the baptism (or dying before the baptism etc.), this is now the only choice that can be made, as the other choice would lead to a paradox and hence delete itself.[/spoiler:087c04a341]
