Donnie is so happy!
(possible spoilers if you havent seen wormquake yet)
LOVED the development here, cuz at the beginning it was clear Don and Casey didn’t like each other. THEN when Casey’s caught in the worm, Donnie shows sincere concern for April’s feelings and isn’t at all jealous or angry with Casey, and then here we can clearly see Casey smiling and neither of them are as hostile towards one another and it’s all I could ask for! :’)
