wet interior

[CamrySExxx]

well... we have the leather seat covers in our SE and my sister drove the car, parked it in the drive way with the windows down and 30 minutes later there was a rain storm. 2 hours later i go to pull the car into the garage and notice the windows down. I tried to get up as much water as i could but the seats were still damp. What should i do? the leather feels different (right side was more wet than left) and sorta dry....
