I think it would be brave of Sam to go for Ellie knowing that this is likely to result in him becoming unpopular with the public, most of whom seem to be rooting for alex to pull.
Unless there is someone who he already genuinely likes (maybe Georgia?) then I suspect he knows that it would go down well with the public to go for Zara (my hope), and Adam cant complain having done the same to Niall. , But if she is really keen on Adam it may well backfire as a tactic.
So overall I hope he goes for Zara for entertainment value, but think Georgia may be a safer option for him (I dont want him to go for Rosie as it will go to her head, any anyway she is "heartbroken")
I think Samira has 3 chances of being saved:-
- Sam picks her (seems unlikely so far)
- Sam picks Ellie, so Alex picks her again
- Sam picks Zara and Adam decides he wants Rosie out
If is is not Samira, it will be Rosie. Can't think of any scenario that would result in anyone else going.
