Well since the renewal for Lie to Me for another 13 episode season has just been announced (several times), not much has been said on what will happen in the second season as of now. But I CAN tell you that there will be a development in the 'Callian' relationhship and more will be brought up on Cal's past.

WHAT?!?!?! Only 13 epsiodes?? They need to renew it for a full season (23 or 24 episodes)!
I was very pleased with a spoiler given by Brendan Hines in relation to Season 2. He said that Eli/Ria is also happening, but it's going to be complicated. And boy, am I excited :P
