"Professor..." Eino began with his hand right in the air the second Professor Williamson had asked them if they had questions. Eino had two, actually. One was more of a concern, though, that had evolved into a question within three or four seconds. "Regardless of how hostile the grindylows might be, I must admit I am not very comfortable hurting them. May we receive permission to use the Tickling Hex as another possibility. After all, no one can resist a good tickling." Eino's seriousness and gentlemanly tone contrasted greatly with his last few words, almost making him sound comically sarcastic. Though he truly did not wish to harm the creatures, he had never encountered out and experienced just how nasty they could be. "Also, do you intend us to master this spell non-verbally or will we be able to use the Bubble-Head Charm?" He finished and looked at the professor intently as he waited for an answer. He did manage to grab one of those snazzy suits as he spoke, too.
