Tension is escalating leading up to the finale of Big Brother 17 tonight.

Who Will Win 'Big Brother 17', Liz, Steve Or Vanessa?

Final 3 houseguests: Liz Nolan, Steve Moses and Vanessa Rousso

Steve and Vanessa will face off in the final part of the HOH competition tonight, with the winner gaining an automatic spot in the Final 2. They will then have the sole power to evict someone and bring the other to the Final 2 with them.

'Big Brother 17's Vanessa Has Essentially Confirmed Her Final 2 Plan

As it stands now, Steve is still set on backstabbing Vanessa by evicting her and taking Liz to the end if he wins HOH. Meanwhile, Vanessa seems a little less sure in her decision but based on the amount of assurances she's given Liz throughout the week, it looks like she would evict Steve.

So this final part of the HOH competition will likely determine who wins and who gets third place. Liz essentially has an automatic slot in the Final 2, but it seems unlikely that she would win against either Vanessa or Steve, even with Austin and Julia in the jury.

Yesterday was another quiet day in the house though Vanessa and Steve did decide to come clean to Liz about their Final 2 deal. Vanessa said she made the deal on Day 40 as a way of countering the Austwins alliance. Liz pretended to be surprised, but Vanessa had already told her previously that this conversation would be taking place and that she would still be taking Liz to the end anyway.

Steve talked to himself on several occasions throughout the day about evicting Vanessa, seemingly trying to convince himself to make the move. Would he chicken out at the last second if he won HOH? It's certainly possible, though not probable.

Either way, this should make for a suspenseful finale night for the first time in a few seasons. We can't wait to see how it plays out.

Big Brother 17 airs its finale tonight at 9:30 p.m. ET/PT on CBS.
