Before Thomas goes to talk to Teresa, Minho reminds him not to listen to a darn thing. Minho doesn't trust anyone.
Teresa begins by telling Thomas that they looked for his group but couldn't find them. In fact, they didn't leave Thomas behind; they thought Thomas and his group left them behind. Ahh, the miscommunications.
Thomas isn't having any of it. He still doesn't trust Teresa.
Anyway, Teresa adds that WICKED doesn't plan to stop the Trials until they get their blueprint. Despite his saltiness to her, Thomas believes her.
But it's also strange that Teresa agrees with Thomas about WICKED now that she has her memories back.
Teresa pleads with Thomas for him and his group to join back with hers and do something. But Thomas just responds, "We'll see what happens" (44.26).
