Phil said, "The Final 4 head to Hong Kong... where costly mistakes lead to a shocking finish," in the preview... doesn't necessarily mean elimination.
I think Tiffany & Krista are out. They seem most likely to make a fatal mistake (that comes with a penalty) at this point of the Race. I would say Logan & Chris are most likely, but they were already spotted in F3. Plus, I don't think they'd flat out spoil Justin's reaction to
elimination. Something more than just "arriving last" happens
and neither Tiffany & Krista looked happy.
My guess is Justin & Diana do arrive last (in a close finish) but someone (guessing the Cheerleaders) gets a penalty.
I need to see Kelsey & Joey's faces again. Or the preview altogether. Who was at the Pit Stop together and who was not?
ETA: I said all this as a fan of the Cheerleaders. Heartbreaking.
BTW, after the tattoos by Diana and the random arguing arc for like 2 legs, I don't think they're eliminated
