You mean this tiny figure in the background?See, look at where the first Naruto that Madara notices is; He is infront of Kakashi.
Now look at the last bottom right panel, you see another Naruto who is behind Kakashi.
There are 2 Narutos..
Maybe this is Naruto (it's too small to tell, even after enlarging the image), but even if, it's no proof that there are two. Naruto may have moved closer to Bee, there are even lines in the panel that could indicate movement or a sudden appearance. Considering Naruto's speed, this is not impossible.
Plus, in all the previous pages that I have posted in this thread, there was only one Naruto since the moment when his clone smashed Tobito's mask.
In my opinion, there is no evidence in the manga about what happened to Naruto's clone that was in the second Kamui dimension.
