well, if she's a bartender at the roadhouse, chances are she knows alex! she always hangs around that place. she might view marlena as a younger sister type, and secretly wonder if she's the appropriate age to be working in a bar haha. is there a reason why she's uncomfortable with hunting? because if alex were to ever find out that hunting doesn't come easily to marlena, she might offer to show her a couple self defense moves since she's known how to fight since she was a girl.
