Nott watched as Potter found his way to the Gryffindor table in a quite clumsy matter and curiously watched for lack of a better thing to do while chewing on his food. He wasn't expecting the block to turn and address him... Err, what to do? Now knowing how else to act, Theodore made as if he had never heard the question, blurring his sight and staring randomly ahead. It might work, seeing his surname was so... particular. You know, he could have been asking "Can I help you not?"... which would be a strange question, yes, but posible nontheless, for it did sound like that. No need to show he knew otherwise... Though Potter was looking his direction.

Well, no Potter nor Weasley have been the smartest blocks in the book so they might fall for it, he pondered, still staring ahead.

ooc- actually, Nott is in the Slytherin Table, while the trio is in the Gryffindor Table and they have the Ravenclaw table in between so it is most probably that Nott hadn't heard Harry's question (nor Hrry would have attempted questioning) but no matter, let's make as if they were closer so to make your post fit^^
