I really didn't like the 8 and 8:30 slots going to Adventure Time and Regular Show like that anyway. I really dislike how the nighttime line up was so Teen Titans Go! heavy, especially when they could have easily fit a nice rotation of the shows in the 5-8 PM slots as they have been doing anyway. I hate to admit that the 8PM Adult Swim line up worked for the best, but it did... at least in terms of the CN programming not crossing with mainstream television episodes.
Besides, this week just has more TTG shows in the 8PM slot, as well as Gumball with no new episodes. I don't think it's much of a loss anyway.
