When Tom the paramedic arrived on the scene there were not one but two shots of Ben looking REALLY uncomfortable, rubbing his hand over his mouth. When I rewatched the scene later on it made it seem obvious to me what was what save for the fact we never saw Tom look in his direction, only toward Jane and then to the hockey stick.

Well i had him down as Lola's mum but good shout.

Nope.

Or it could be that Ben was concerned that the paramedic would work out that Jane had been hit on the head with something rather than her injury being the result of a fall.

Ahh, that's what you meant in the Sexy Paramedic thread! No, I'm pretty sure Ben was just worried about Tom finding out what was going on. I really hope it wasn't Tom that passed on an STI to Ben, you'd think he'd know better as a trained medical professional!
