Tub and Tonk are great siblings, but the facade we've come to know had masked a tragic backstory. In the previous chapter, it's revealed that Tub's parents were killed. How exactly hasn't been revealed yet (please help me find the artist). Anyhow, in this chapter we come to find that not all is fun and games between the two. It's revealed that Tonk has had a history of smoking and alcohol intoxication behind the scenes. Tub has tried to stop him but Tonk is incessant. It's quickly gathered that the bloody scene Tonk saw that day left him traumatized and shook. He has constant flashbacks and only cigarettes and alcohol can distract his mind. We've come to find that Tub had managed to convince Tonk to put the cigarettes down, but this wasn't meant to last.
One day Tub went outside and smelled the all to familiar scent of cigarette smoke. She stomped towards the source, knowing all too well Tonk was behind the source. He had given in to his addiction once more.
She walks into the building. There's a black and white checkered floor, and right at the end is Tonk, sitting hunched over smoking a cigarette. Tub is vastly dissapointed but not sruprised and asks if he's smoking, if he has given into his addiction once more. But Tonk immediately shakes his head. "What's he thinking, sigh...", thinks tub. Obviously Tonk is smoking, why is he lying?
But Tonk wasn't lying. Surely he was smoking but he was not trying to hide anything. And he points at the door. The door behind Tub was open as far as she remembered, why is it closed now!
