Can I continue to complain about the random appearances of Head!Shrink? Well, I'm going to anyway. ;) Given the mixed emotions Kev was dealing with in regards to his choice to leave Gog to die and believing he took the van, when it was actually one of the fire trucks, without question he has psychological issues he's not dealt with. My assumption is Head!Shrink was to show us throughout the previous seven episodes something was wrong, and, yeah, she did to an extent. But when she's MIA for entire episodes or pops up briefly and randomly it does not work as a plot device. And shouldn't she have appeared again at the beach? Or was she replaced by a vehicle? :p
I am curious if, in a second series, we pick up with Kev in therapy, knowing he has a problem and dealing with it, or we get more hallucinations as he continues to try and cover and be in denial. I really hope it's the former.
As for his choice to allow Gog to die, I'm torn. There was a nice parallel between Kev and Rosa and their inability, no matter how much they try to show the world they have moved on, to deal with the destruction and pain one man has caused them. Moments after Kev tells Dennis he's not turning him in because, if Rosa can put the past behind her and move forward, so can he, he sees she is still in the throws of her grief. And it's because of the grief that neither has truly dealt with they make the choices they do. (Though, as a mother who lost a child, wouldn't Rosa have made sure Emily wasn't home? I don't think she could have lived with herself if Emily had died.)
And even if it was Gog (who I do think could have been written a bit more subtly at times) and we know he likely would have continued to hurt more people, I hate that Dennis was put in a position to leave someone behind to die again. Though, it does set up a nice bit of role reversal in which he's left to judge Kev and his actions and he's keeping Kev's secret.
On a superficial note: Shirtless Jamie Bamber. Twice. :) And Trish not wearing matching underwear. Because how many TV shows and films ALWAYS show the actresses in matching underwear. How realistic is that ?! ;)
