Central Dome Fire Swirl Question

[Nern]

I was playing this quest earlier and noticed a guy named oswald in the item shop. I talked to him and he said something along the lines of "sorry that i confused u with someone else but dont u have something to show me?" Anyone know what this means or if does at all.
thanks
