Paradise has introduced several unanswered questions, but Alex's identity might be the most mysterious of them all. Season 2, which premiered in February, mentioned Alex as an enemy Link (Thomas Doherty) was determined to kill after finally finding the bunker. The name was mentioned again when Sinatra (Julianne Nicholson) got out of the hospital and asked a paid cleaner how Alex was doing, which hinted at a secret project taking place behind the scenes. Gabriela (Sarah Shahi) started to look into Alex by bugging Sinatra's office.
