In the early episodes of OFAH, Trigger is displayed as a more balanced character. Part villain, makes some silly comments but also some shrewd ones. Is generally shown as a faithful mate to Del and Rodders.
In Yellow Peril he is shown as a small time villain / thief.
Second Time around he is giving good advice to Del not to get involved with Pauline, and Del is an idiot and ignores this.
Ashes to Ashes there is a clenched fist threat to "someone" (Grandad has been seeing his Gran years ago, but Trig doesn't know).
Losing Streak he is being a good mate to Del (offering his car), also the coin toss suggestion.
To Hull and Back doesn't really understand Rodney, but then Rodney looks like an idiot as Imogen is cheating on him anyway.
Tea for Three - possibly smart as he gets Del and Rodney to entertain his sister and doesn't tell them she is engaged?
In Video Nasty he is laughing at Rodney (along with the others) in the pub, again Rodney looks like the idiot with the mix up on the naughty video in the flat. Also does his James Cagney impression.
In the Frog's Legacy he has a funny moment with Rodney and Albert "she was gonna get married than she found out she wasn't"), where he comes across as sharper and Rodney looks like a dimwit. Rodney then looks like an idiot at the funeral to boot.
In Dates "I can't believe it - it's a woman". He seems to be getting on well with his date.
Seems like from series 6 onwards he became more of a target for punchlines as opposed to his own character. I love series 6 but didn't like Trigger in those episodes.
Chain gang, Yuppie Love, Class of 62, Mother Nature's Son, Heroes and Villains I like these episodes but trig is purely an idiot in them
Final awful trilogy spawn of satan - idiot in these. Painful to watch.
