I was dithering over the course of that episode after the initial revelation that Gene had already copped it, as to which side of the coin Jim and Gene were supposed to be, but then the snarling psychopathy coming out of nowhere and that elevator nudged me the right way.
Midway through that series we met a former partner of Gene, Ray and Chris, who claimed delusions of being Sam Tyler. I'm rather puzzled by that loose end, as what he was coming out with seemed insider knowledge, and notably, quite a fair chunk of cosmetic fiddling made him quite a Sam Tyler Ten Years On, and his maddened focused glare looked as if he was channelling John Simm's depiction of The Master in The End Of Time finale episodes from Doctor Who Ten. But I dunno.
Wasn't too fond of the revelation of Alex's fate to be honest. What made Ashes different was her driving force to escape home and be there for her daughter's birthday party, but to make it a loose repeat of Sam and have her dead and stuck in the police afterlife, with just a stoic Gene to brush off the fact that Molly will have the support up top in the real world, seemed like quite a downer ending.
Personally wasn't fond of Shaz, the "are they aren't they" back and forth with Chris, not to mention her accent and RAR-RAR-rampant-feminism-"oooooh Michael Foot would make a great Prime Minister" jibe. But a good move to bring those three supporting characters as one unit forward to the limelight with the staaaaaaaars arc.
I thought Martin Summers in the second series was a great character, very mysterious, nicely pulled-off. Interesting how Alex goes into that coma-within-a-coma from her bullet wound in 1982, thinks she's woken in the present day hospital, sees a body wheeled past her - allegedly that's Summers, and his death in the "1980's" implies death in the present, but Drake wouldn't have seen it at all in reality.
