There was a time were Samantha had a girlfriend. (Samantha is bi btw.) but of course not all relationships work out. lets just say this one did not last long. poor Samantha still has some PTSD from the break up, so she's not comfortable when its brought up. she's still healing from the scars. if you want to talk to her about it, is best if you let her take her time to even mention Rachael's name.

don't worry her character comes back stronger, and happier.
