The only reason why you're talking to him is because you're DESPERATE for energon atm, and he happens to be uncannily good at finding energon sources.You were weak from your lack of energon, unable to fight back if anything came at you. Octane walks up to you with a cube of energon. he doesn't give it to you, he looks down at you on the floor and grins "You know, I would expect a 'thank you Octane!' But you seem too weak to even say anything! Too bad! cause you gotta do smt for this energon!"
