Andy's pros and cons for each person leaving (from his talk with Aaryn):
Jessie is dangerous because she wants to make a big move against people he's aligned with, however she's not coming after Andy. Always know what she's thinking.
Spencer wouldn't go after Andy's allies anytime soon, however he is a good liar and might not always be sure where he's coming from. So good at manipulating people. Smarter than Jessie and thinks things out. (Aaryn says Spencer may make a big move against Elissa/Helen).
Says he's leaning towards getting rid of Jessie, but wonders if she stays if he and Aaryn can get in her ear.
