IMO GDL should've come to America at the end of July and been here in August so he could get some guest spots on the shows in major production now for the fall season. He had all the press from COE (it would've been perfect timing) and if he wants a better chance at landing a pilot, a few guest spots in American TV could help pad his resume. But then he didn't consult with me...

"I reckon the only way Ianto MIGHT return is if Jack becomes mortal again and he's now able to have a normal relationship without sulking about it."

Wouldn't that be nice? But alas...not holding my breath.
