Rorschach looked at Stevie for a minute silently before talking. "I'm totally gonna build a secret den or like a super hero lair, that'd be pretty cool right?". Stevie merely tilted his head in response. Rorschach took that as a sign of approval. He was bored, he needed something to do, he needed a project or something similar. Therefore, in his mind, the only thing to do was make a secret lair, like it would be the most normal thing to do. 

He got up and went into town, looking for a DIY store, wondering, in fact, what we was going to buy. Some planks of wood was going to be the first thing, from there….. he didn't know what else. He spent quite a long time in the store, buying just about anything he could lay his hands on. Finished, he started wheeling back the two massive, loaded carts of random things back to the spot where Stevie still was at school.
