From what I've seen on the unofficial scans, it seems Gon only says "aiko". It perplexes me too, but I don't know where I could find the raws. However, in teh 2011 anime (I just checked, episode 89), Gon says "aiko de", with Knuckle only repeating "aiko", so it may indeed be worth double-checking, if you know how.
