Can anyone tell me what season we are watching?

I am watching on INSP. Tonight's episode is "The Secret" I am seeing episodes I don't recall from the first time around. After I went away to college I didn't get to watch. There were no tv's in dorm rooms then and there was only one in the common room. So I am really enjoying watching, but I don't know what season we are in.
