I have wanted more Sakura screen time/focus for most of the series, though this isn't exactly what I had in mind (at least what it was implying). Hopefully, not a bait-and-switch gag
Edit: It just occurred to me that they might do something stupid like empty the water jug, cut off the bottom and shout through it to communicate or something. Just want to throw the idea out there in case they actually go that route
