...welp, this does seem like it might be the end of Vriska. It's not possible to be SURE, really, because no matter how just one of us might think the death is, it depends on what Hussie thinks. But we'll see.
It's quite interesting to know that Vriska would actually be able to damage Jack, though. Makes one wonder how she'd be able to do against him with multiple God Tier partners helping out.
It's a little irrelevant though, since Doc Scratch wouldn't let such a thing occur if it WAS possible for Jack to be beaten; he needs the Green Sun blown up, Jack dying beforehand would means his pawns don't have a particular reason to go to massive effort to blow it up.
