Right, so I think what'll happen is Ed will help sneak Matt off Tattoine. That way Ari and Yerbol don't have to go to Tattoine and risk being exposed AGAIN xD 

Wild space...would it be plausible for Roan to have gotten a very loose outline of a star map while he was "tying up loose ends"? It doesn't have to be a complete one, but maybe he thought it would be beneficial to raid some of the archives while he was on Korriban and found a very old map with fragments coordinates? If they had that, Neta could then get them to Wild Space.

OR

Yerbol and Ari already traveled to Wild Space once. Who's to say that they couldn't input the coordinates from their journey there previously? That would assume of course that they could remember them xD
