PLL 5x19 Trailer: "A" Has Get-Into-Jail Blood Donations

Will the Liars soon be sharing a jail cell with Alison?  In the preview of “Out, Damned Spot”, "A" texts a photo of blood vials labeled with Aria, Spencer and Hanna’s names.  (Does “A” not have Emily’s blood?)  The text message is “Thanks for donating to my get-into-jail fund.  – A”.

Aria is concerned Alison will destroy Mike.  She demands to know what is going on with Mike, but he refuses to talk and slams the door in her face.

Spencer sees a newspaper article about vandalism at Hollis College.  She immediately confronts Johnny and tells him that she can’t get arrested again.

And whose window is Mike peeking into?
