Who did Mona choose on half and half?

Answer 1

While it's not an official answer, a source on the show that posted on Television Without Pity said that it was likely that Mona chose Chase. A case was made that if Mona chose Lorenzo, she would've ran up to his apartment to tell him as opposed to calling on the phone.

Answer 2

At the end of the series this is left up in the air, so there is no certain answer. On message boards talking about the show afterward, most people think that Mona ended up with Chase, but there are still a lot of people that wanted her to end up with Lorenzo or even Spencer.

Answer 3

I think it is chase because before they broke up he said i dont think you know where your heart is and when she called the person she said i know where my heart is it belong to you
