Wouldn't Lumen have changed her cell phone number by now?

Dexter's revenge-seeking protégée, Lumen Pierce (Julia Stiles), has been off the grid since Dex sprung her from her captors — which is why it was so jarring to see her cell phone ring with her ex, Owen, on the other end of the line. Wouldn't she want to ditch her old digits, considering that her tormentors are still out there?

"And wouldn't she want them to call her? It might give her an opening to track them down." Can you hear her now, sickos?
