Ian noted the professor's response to his answer. He was content to know that it wasn't completely wrong or dismissed outright.

When the professor instructed them to get their jars and gloves out for a bit of fairie hunting, Ian bounced a little bit. This would be kind of like fishing. And, that would explain the giggling when they came in. This probably wouldn't make the fairies terribly happy though. Probably why the gloves were needed. He reached into his satchel, pulled out his gloves and jar and followed the professor into the bush opening he'd created.
