Season 5, episode 3.

Alison gives Rachel Leekie’s head.

When did Alison get the head back from Cosima? I remember Scott discovering the tumor was fluorescent. The tumor that was in Leekie’s cheek.

Then what happened to the head?

When did Donnie and Alison re-cover the grave in the garage? In the S5E3, the head wasn’t in the grave. Was it still at the comic book store? Hubby says he thinks it was and Alison went over and retrieved it to give it to Rachel.

I’m so confused!
