Lester Dialogue
"You know, sometimes I wonder where I'd source half of equipment. If it weren't for this great country's abundance of private security contractors. Tonight's shopping list, courtesy of Merryweather Security, includes stealth equipment, night vision goggles and noiseless covert rappelling gear."

- If the location is at Fort Zancudo.

"Ah, Humane Labs. To some, an impenetrable blacksite for ethically dubious research. To us, a 24/7 convenience store, freshly stocked with stealth equipment, night vision goggles and noiseless covert rappelling gear. Oh, and we might need that last one in the casino elevator's busy. So, head over there. I'll be in touch."

- If the location is Humane Labs.

"Alright, listen in. The equipment is all boxed up and ready for transport in their next shipment outta here. You'll need to hack the control panel to get inside the lockup."

- After reaching the locations.

"That's the good stuff. Lose the cops, and get back to base."
