Judging from last night, we can choose between Theo, Megan, Carl and Maggie. Oh, and Shona's sister. None of them would be a miss, to be honest, but I'd rather see Theo meet his maker.
Megan adds nothing for me, and Maggie has been a disappointment. Carl is a villainous baddie, but we need a 'love to hate' character, and I know nothing about Shona's sister other than that she (inexplicably) seems to fancy David.
