I assumed that it was because it was more or less implied Lorena pushed her way in on what was probably supposed to be a dinner date between the two of them -- it was a restaurant where she obviously couldn't eat the food (fish, yet ordered it anyway), her body language conveyed that she didn't want to be there (so why not go with any of the other team members doing something else?), and Jaime basically thanked Eddie for coming as a buffer. I think the "girls fighting over a boy" trope is overdone, but I can't say I'd be the picture of patience in the same situation.
