She said wanted Marley to win in that interview! She's been very pro Marley on social media which makes these rumours seem likelier....
I'm positive that Danny will get evicted before the Final 4. In the promo for next week Danny & SJ are both seen competing in the Top 5 challenge (thanks to eagle eyed YouTube commenters). Also I think Marley will win the final challenge. Christina would take Ari to the F3 (given they are friends, and he's hardly a threat) and it makes sense that Ari has grudge against Marley. I feel like the edit is so readable, they've been showing us a lot of the SJ/Marley bond recently and even him getting along with Christina...
