Derek vs Eugene was the worst of those because Eugene was a disgusting little worm, while Derek was a star

Maybe worse than Science vs Orlaith.
Freddie already ruined the series by knocking out AngelFromHeaven and IAmTellingYouOnMyFace, so **** him. Siavash vs Marcus was disgusting and I stopped watching after the Irrepressible Dark Horse left.
Lydia vs Deana was a lose-lose one, like Dexter vs Sallie vs Gina or Caoimhe vs Sunshine vs Shabby (which was a terrible result since the other two eventually quit)
