Though he had done his best to elucidate - that meaning ‘explain’ - the situation to the madam, he didn’t need to be as smart as he was to realize with the other’s gestures that most of what he said had flown right over her head. Hm. His allies sometimes explained that was a bad habit of his, to use lengthy words that they could not understand. Perhaps he should try again, but simplify matters as much as he could.
He honestly didn’t understand any of this puzzling behavior, but then again, he was alone in the desert for five years. Not like he knew all too much about social conversation. Though, as he pushed his glasses back up his nose to prevent them falling (and slightly to stem his own bewilderment somewhat) as he was about to attempt explaining the matter once more, the madam paused in her observations of him, her eyes locking on his rounded spectacles.
…Wait, who in Yilesse’s name was Shinpachi? That certainly wasn’t his name. This madam clearly had the totally wrong idea about him, that much he was able to note. Rubbing his arm slightly at the ‘exuberantly friendly’ punch to the arm in greeting, his eyebrows raised as the madam continued to muse the wrong idea, asking why he did not say who he was, or tell someone called Autnie Kagura.
"Now, see here, madam. I most likely look nothing like this Shinpachi friend of yours: and I can verify I am not him. I am Laurent, as I said before. I have not heard the name ‘auntie Kagura’ once in my life, until you told me just now. Nor do I believe we have ever met up to this point."
A pause, he musing: "I can understand if you miss your friend, and want to think he is here. But to prove I am not him - can your friend use magic like this?" He paused to open the tome book he held, turning around so the magic would not blow the madam over or anything, and shouting: "Wind!"
As he shouted, himself and the tome he held glowed a light blue - a gust of magically glowing blue wind shooting from his outstretched hand, blowing through the hallway a bit before fading away - wind was his weakest ‘wind related’ tome, he had no intention of using powerful magic in here, goodness no!
Once the magic faded, he closed his tome book, to face the other again.
"I trust…that proof will suffice to show I am not this ‘Shinpachi’ fellow? I honestly would not wish for you to get the wrong idea and then be upset once you figure out I am not him - so I wish to clear this matter up for your sake."
That said, he could only hope the madam realized what he actually was, now. Though she seemed so ingrained to the thought of him being her friend that he wouldn’t be surprised if he’d need to show more proof.
