Dude, I hate to say, but learning a certain scale is not gonna make you be able to play jazzy... I suggest listening to jazz songs and trying to emulate what they play... listen to a song a hundred times until you can play it with him (AND DON'T CHEAT BY LOOKING UP THE TABS!!). This is how all the greats learned to play, and it's so you get the sound of jazz in your ears and in your fingers...
