Cesar's cousin turns out to be Catalina, and Carl meets her at The Welcome Pump in Dillimore. She is not interested in a date and she is not pretending to be: she has already cased four soft targets across Red County and she wants a partner for them.
The four are a liquor store in Blueberry, a bank in Palomino Creek, a filling station in Dillimore and a betting shop in Montgomery, and all four open up the moment this scene ends. There is no gameplay in the scene itself — it is the briefing for a strand of the campaign the player is free to run in any order.
—No gameplay. This mission is a cutscene.
