I Know You is the fourth episode in season 3 of Infections.


Monica and the rest of the group are struggling to get along after Wes and Chase both died and Abby, Liz and Mark went missing. When they stop, Lucy attempts to talk to Jenna, who coldly tells her to "Fuck off." The group hear something in the woods and are startled when MacKenzie James exits.

Kenzie asks Monica what happened to Vince and she tells her about everything.

Kenzie leads the group to a gate when Quin, Denise and Amber yell for them to stop as it is their former camp. Kenzie shouts something and a group of people attack, taking everyone except Amber, Jake, Mikel, Kaya, Danni, Jenna and Lucy, who run away. The others are taken captive.
