Sally's brother shows up with paperwork that proves he's the new landlord of the brownstone. She's freaked - if he sees her, he'll die, per the curse. Fun fact: Sally's brother is played by Meaghan Rath's real life bro, Jesse
Max observes Sally's upset, but she won't admit what's truly going on (since it involves revealing she's, essentially, a zombie).
The worst thing that could possibly happen does (hey - it's a drama, are you shocked?) when Sally runs into her brother. Desperate, she heads straight to Donna the witch.
Sally makes a deal with Donna - she'll give up her soul when she dies to Donna in exchange for those that recognize her not dying. This came after some threats to Donna, where the latter threw Sally and Josh around with black magic.
Sally tells her brother she faked her death before he leaves town. She also makes up with Max and apologizes for keeping him distant (she still doesn't confess she's a reanimated corpse, though, natch).
Meanwhile, Kenny gets Aidan to confess he's a vampire. Wanting to be free of his isolation tank, Kenny begs Aidan to turn him.
Which leads us to flashbacks of when Aidan turned! He was a soldier in the Revolutionary War when he encountered a very hungry Bishop. Both needed a comb.
Here's the episode's big twist. Teen wolf Erin is working for Liam, the evil werewolf. Per his orders, she taints Aidan's clean blood supply with her werewolf blood (which is bad for vamps).
Weakened from the bad blood, Erin stands over Aidan, ready to strike.
