As you were looking around the lab, and wandering around - you saw some two. Who are they? You heard them talking.

Supaha: Come on, Kalaha. You literally can't just be toxic to random people. the experiments in this lab hate you, y'know?

Kalaha: "Well I don't care!"

The other known as Kalaha is rather rude... And Supaha is telling him to stop. This was strange, because you have never encountered people in this lab before.
