Remember Sree pursuing Noirin? I know he was a proper headcase with his obsession and lack of social awareness, but Aden could be heading that way I reckon...poor lamb.
Least Aden does seem to be more self aware so far, eg playing down his feelings when he was chatting to one of the other lads last night, but I can see that changing if things go on as they are, with Rebeckah telling him again last night that she still fancies him (yeah, right).
