Mark,Shaun,Anne and Paul are quite likeable in their individual ways but Jenny Ryan carries it a bit far and I get the impression she means it whereas the others always seem a little tongue in cheek.
//Jenny Ryan wrote questions for the pilot episode of The Chase in 2009, She joined the show in 2015, making her debut appearance on 2 September.She was recommended for The Chase by Anne Hegerty, as the two of them competed together on the same quiz team.//
So Anne rated her, maybe it's her Bolton wit (?) that lets her down?
