Did you have to eat the dude earlier in the game to have enough power to scare Jake off after revisiting the frat-house? Or was choosing the Power option instead of Skill option during your 1st boxing match enough? I tried a play-through where I gathered all the power I could and one where I gathered all the skill i could- but I didn't try the middle route. Hopefully it is- I liked scaring him off- but I didn't really like eating that thug. I'll have to do a cannon run after the next release to get the right balance ;-).
