Oliver managed to keep himself from chuckling at Katy's comment. He thought he was behaving just fine. He was here to offer his opinions and comments and that's just what he was doing. But he'd also take the compliment. He nodded at his friend and then looked to his partner, Kathleen smiled at him but something in her smile seemed unsettled. He smiled back anyway, not having a care in the world really.

"Jesús has some fixation with the piano and i'm sure he's onto something there.. Honestly is a weird riddle but it mentioned Scores and Keys and that sounds like a piano to me! But what could be inside? It's a Grand Piano so it's a decent size." Plus magic was a thing so it could be even bigger on the inside.

"Valerie Gray is reading the riddle very carefully. It's very important. Every word in a well crafted riddle is there for a reason so memorizing those words could be key here. .. She's draining the bathtub?
Huh.. Interesting. Oh! I think she's found the Piano!" Clearly it was something they needed to find here.

"Apparently Brent Westwood thinks this is a cleaning challenge...He's got no concern for being quiet and he's using the bubblehead charm? Out of water? What is he doing..?" Oliver was concerned for his housemate, he also wanted to laugh a little but that would probably be too mean. "Now the house seems to be throwing him a bone, the piano and the stove are trying to get his attention since he isn't sure what he's doing... and now he's messing with the Piano? Nope.. now the stove.."
