Brilliant show, can't for the life of me work out who H is but Hastings has shown himself to be corruptible due to the £50k he gave to murdered John Corbett's wife - he also had the laptop at his place in a previous series. Arnott now doesn't trust him and he gave Arnott's drug habit away to the testers after telling him he'd be alright which is out of step with what he did above.

Really does keep you guess doesn't it - "give me strength!"
