Jake and Liberty are a couple facing some serious adversity at the moment, but it's hard to be sure about what's really going on. They've been coupled up since the very beginning and only recently been seen to have doubts. Mostly, the public (and the girls in the villa) are questioning Jake's true feelings, and we continually struggle to watch him attempt to reassure Liberty only by constantly reminding her that she's his girlfriend (she knows, Jake).
They were once shoo-ins to the final, but it seems that Jake's recent behaviour and Liberty's uncertainty are rubbing off on all of us, and we don't have the same confidence in them that we once did.
