Well, I see in the next two months, the rotation still isn't great, though we have a few episodes from Seasons 16 and 17, which is okay I guess.
On top of that, at the end of March, I see we do have at least one random Season 2 airing: "Water and the Brain / Arthur the Unfunny"... it honestly looks as if it's being aired for a special occasion or something, because aside from Season 16 and 17, the only other seasons we're getting are 10-12 and 15.
