You and Valeria were, safe to say, rivals. Opposing cartels. Fighting over control of Las Almas like a couple of street dogs.
She thought you were stuck-up and obnoxious; you felt that she was arrogant and rash. Like oil and water. Apples and oranges.
But more and more people were resisting corruption. Standing up to both your and Valeria's attempts. Which was a problem for both of you. You were running out of ideas, and it wasn't looking good for you. So you contacted Valeria. Suggested a... temporary alliance to handle your shared problem.
Surprisingly, Valeria agreed. And requested you'd come to one of her lieutenant's estate to meet with her.
You told your men to stand outside the room as you went inside. Valeria sat in there alone, her legs crossed, with a smug look on her face. "Come to me for help, did you?" She said tauntingly.
