    Although viewers are still waiting to hear whether One Tree Hill will get another season, at least one wait is over: After a two-month hiatus, the CW series is back Monday at 8/7c for this season's four final episodes. James Lafferty, who plays Nathan Scott, one of the only original characters left,  tells TVGuide.com there are "really gratifying moments for those fans that have hung in there." Read on to see what Lafferty has to say about the season's last episodes, including some big decisions that will be made and where the series stands at the end of the season.

TVGuide.com: Before the show's hiatus, Haley's mom died. Will she and Nathan still be dealing with the loss when it returns?
James Lafferty: Yes, absolutely. There's definitely a grieving process. Not to make it sound like it'll be all gloom, but that's Haley's journey ... and she's going to need help and that help is going to come from her family unit.
 

 TVGuide.com: What leads the gang to Utah in the finale?
Lafferty: Julian's film has a certain amount of success, and that's why we're in Park City, Utah. For different reasons, they decide not only do they want to show their support for the film, but they want to get out there to blow off some steam and have a good time. There are actually a lot of big decisions that are made in that town, and after the characters come back to Tree Hill, a lot of big things will happen.

TVGuide.com: So is there another time jump?
Lafferty: That's a good question.  I don't know if I have an answer there. It seems a little quick for his film to be edited and already submitted, so maybe we did jump ahead a little bit.
