Episode 4

S2 E4: As the housemates strategize how to take down the power couple in the house, a new guy has easily emerged as the most unpopular guy in the pad, and one woman shows her true colors. Meanwhile, this week's challenge is the "Kissing Challenge." Each guy will kiss the women - and vice versa - then vote for who has the "best lips" in the pad. The winners will be treated to the first one-on-one dates of the season.
