Mystery Tennyson twins

Another crossover of Gravity Falls and Ben 10 Omniverse in which i finally turn Ben and his twin with no Omnitrix to be dressed as Stanford and Stanley! So the mystery twins are: Stanford Tennyson, and Stanley Tennyson. Since i drew the kid versions of Stanford and Stanley in the Gravity Falls episode A Tale of two Stans. I wonder what should it happen when Ben shows to his best friend Rook Blonko when he dressed as Stanford?
