So... Gio is going to leave the Q's... where is he gonna go?
Well... he has no reason to be mad/upset with Rocco... he now knows Rocco is his brother.
The reason he finally knows his true parentage is because of Lulu (him overhearing her talking to Lois about it)... so maybe he feels inclined to be appreciative toward her (poor delusional guy)...
Is it possible that he will move in with Lulu and Rocco (and invisible Charlotte)??? This would add fuel to the Lulu/Brook Lynn animosity which the writers seem to like... imagine him living with Lulu while refusing to speak to Brook Lynn! Lulu would eat that up with a spoon.
However, I can eventually see Lulu being the one to help him see that Brook really did have his best interest at heart when she decided to put him up for adoption....
