What: “Manuel! Is everything okay?” bronze trophy
When: During Year Four (El Marrow, revisited)
Where: El Marrow, LSA base
When you return to El Marrow, the first place you'll gain control in is the LSA base, now much grander than when you were last here three years ago. Near Eva, you can find a microphone and a radio. Manny will play around with it, attempting to "call all cars", only to be responded back by Salvador, who went off with Olivia.
Other than the two items and interactions you'd find in this room, the trophy itself is optional. Be warned and focus on getting this as soon as you can, for once you enter the top floor of the Casino, you will not be able to get this during your current playthrough.
