The thing is, she's leading him on a bit. Like, if it were me, I'd say straight out "listen mate, you're starting to bug me, just give me a bit of space yeah?" but in a nicer way, but she broaches these subjects with him and then gives him a hug and a kiss!! Stop being touchy feely with him!! I mean, I HATE him with a burning passion and he's a bloody stalking nutjob IMO but she is being a bit of a tease/leading him on presumably to avoid looking mean or upsetting him and risking getting a vote or whatever.
Lisa annoyed me too, because she seemed to be shit stirring a bit with Noirian and Sree saying to Noirian just to tell him to back off cos he's being a creep, and then telling Sree she's not worth it and she's playing him!?
