They eliminated all my faves!!! wth, and the show is going by FAST

Like were only on episode 5 and it's already down to the final 4. WTH, how are they knowing their contestants well enough. If they started eliminating one at a time it gets to episode eight. Which is like two fewer episodes than last seasons. Plus their both choosing one at the end, how is that gonna play out? The only good person on the show is Trevor. Stupid Rikki had to keep Rosie.
