Hi East....hope this helps...

In last night’s episode, “…About Last Night”, Allison blacks out for 6 hours, not realizing how she got from the supermarket in the late afternoon to laying on the sidewalk under a freeway overpass in the middle of the night. As she begins to realize what she’s done, she’s terrified that she may have killed at least one person, maybe two. (SPOILERS FOLLOW) It turns out that she was actually possessed by a recently murdered woman who takes over Allison in the hopes of stopping the deaths of many other people.
