Jesus salter, one chain slap and it was all over. If semi wanted to kill you she probably could have.
Presumably, stopping to actually slit someone's throat in the middle of a crowded theme park would have attracted enough attention that at the very least Jalter would have been able to effortlessly track Semi down before being able to get away, even presuming any security guards would be effortlessly curbstomped.
Well, at least Salter will get off free now that we can blame Semiramis :D
Why do you think Jalter won't blame Salter for not stopping Semiramis?
Yes, I know, it's illogical to do that, but a mom who already had been a very quick-tempered woman being made angry and worried over her beloved son's safety is unlikely to think logically.
