I'm a little confused with the new sprite prototyping, I thought i sprite can only prototype two times, but that don't count if there is a first prototyped sprite and a second sprite that combine? and Vriska said that Tavsprite should be careful around Jake to not combine the two, but if that is a risk why didn't John who high fived a first prototyped sprite combine?

Rosesprite was only prototyped once and Jaspersprite merged with her which was her second prototyping. Vriska is being overly cautious probably because she doesn’t want another Tavrissprite situation to happen.
