Was Lena pregnant?
After the sex scene between Lena and Ernesto in Ibiza, Lena goes to toilet and throws up.
When back in Madrid, she talks to Mateo about how much she hates sleeping with Ernesto, but is it possible that she was pregnant at that time?? Could it be a reason why he pushed her from the stairs(because he thought that the baby is Mateos)?
Has anyone thought about this?
