After 11 seasons it is done.
My predictions

Will Fiona make an appearance? Doubt it.
Does Frank die? Yup, why would they keep him alive?
What does lip end up doing? Probably rueing.
Do they sell the Alibi,? Why wouldn't they, so, yes.

Ian and Mickey are set, Carl the cop is set, Kevin and Vee are moving to Kentucky, so we are left with Debbie and Liam. I can see Debbie just saying "screw it," and moving out Chicago with no planned destination, but what happens to Liam? Either Kev takes him or Lip takes him is my guess.

I will bet they do some kind of dead or ghost stunt at the end.
