When Jake recognized them, he immediately forgot the idea of gleaning any information, let alone forming an alliance. They were the assholes who had chased Tim and Sarah weeks earlier.
In addition to being hideous, inexpressive, and smelling of cockroach, they only knew how to say "Krish" and the sound was like a cricket chirping with a sore throat that would have been amplified a thousand times.
Under other circumstances, he would have tried to engage in dialogue, but he was not willing to take such a risk. Their futuristic weapons represented a mortal danger for him, not to mention their superhuman physique. The fact that they had survived until now in this labyrinth also proved that their minds were not too shabby either.
In the face of such dangerous enemies, Jake would never dare to underestimate them when he was basically unarmed. For this reason, the two Krishs were deeply shocked when a scorching air blast hit them head-on before they even had time to draw their weapons.
