no problem man - I appreciate your reading through these :).

Both are mostly correct, but the version I have sounds a little bit better. The sentence is initially `there are holes`. I believe the emphasis "really" modifies the verb "are", emphasizing that it's interesting that holes exist. If you replace "really" with similar words, it might sound better - like "and there definitely are holes", "and there certainly are holes" or "and there surely are holes".

I don't know if that helps - it's a trickier english thing!
