Seeing as Vriska can now Time Travel, could her Outburst toward the two Pages be intentional, because she knows Jake needs to do the Page thing later, thus sowing the seeds of needing to prove her wrong? Maybe its Justified is all im saying, Irons in the fire and all.
I really doubt it. Jake’s power comes from having Hope and Vriska is destroying the hope he has in himself making it even more difficult for him to use his powers.
