Well, after buying a 120 giga HDD for my 360, i decided to buy and finally get to play Broken Steel, Point Lookout and Mothership Zeta, and then i loaded my lvl 20 character, and i remember having Fakwes with me, now he doesnt, and in the Overworld map it doesnt show his name, so how im supposed to know where the heck is the damn thing? im not entering every place, now that im finished with PL and starting Mothership Zeta..oh and when i finished broken steel i partye'd Star Paladin Cross, said her to follow me but she stayed in the same position, and when i entered to other cell a message pop up saying me that her returned to the Citadel...WTF!?

He is in the museum of history. If not for some reason, check Raven Rock.

If not even there you ought to wait a few days to see if he returns to the museum.
