^^^^^^^^^^^^ Love it!!!
I haven't really been watching it much recently but I did see the episode where he bought that car and found myself like yeah he has his low moments but then his behaviour swings to the positive and it reminds me more of the mania seen in bipolar (which is can't be due to how all that works for those guys) but I thought:
1. Unhappy with current lifestyle = Check.
2. Leather jacket = Check.
3. Ridiculous kit car bought by a very boring bloke = Check. (Usually it seems to be an old soft top or a motorbike)
= mid life crisis.
So, I'm not sure on this now. You do sometimes drift between moods if you have mild depression like with anxiety disorders but its not a great portayal. A few weeks back he was getting depressed about Peter and the court case which he now seems completely over and it seems to be more about him
