There's always one option... being cautious. She's done nothing at all since being dragged to this place, except eat, drink, be merry & now screw. She's living in Lala Land & she's due for a rude awakening. My only wonder is whether she's so blinded right now that she'll betray or abandon the old group
I think Andrea is a horrible character, but I do think the door is open to her using the governor, or trying to learn more before making a decision to leave. However, with Rick's group guaranteed to clash with LaLa Land, she will be forced to show her true colors....or maybe we already see it with her history of jumping on psychos like Shane & the governor.
