I think the addition of David Eh? so early was a panic move by the producers, after the absolute clusterfuck of letting the public choose the initial pairings. Looks to me as if there is zero attraction to any of the guys by any of the girls (exhibit A, the most cringe game of dare ever seen), which may have been different if the girls had had the option to step forward.
Gemma's inclusion is a nonsense, Paige/Tasha seem alright, and all the guys are brutally one dimensional.
I'm not going to get invested, no way, no chance...
