Series 2 Episode 8 (Poppy's friend)

Who is the girl who sleeps with Marco?! She's not credited (even though she has a bigger role in the episode than the very cute Lucy Evans). I've been to a few websites and she's not mentioned anywhere! I'm sure she's referred to as 'Eloise' at one stage in the episode itself but there is no mention of her anywhere even in the various episode descriptions on IMDB and other websites.

Does anyone know who she is?
I'm fairly sure i've seen her on TV in the UK since but i'll be damned if i know who she is.
