I feel like I can answer a few more questions this time than last time but I'm not sure about all of them still. So anyway...

1) I don't think Gyo works that way. If it did, then you would only be able to see the Nen through the wall and not the person using the Nen.

2) Different manipulators use different tools to manipulate. Not all of them use needles. Illumi and Shalnark use needles that are very clearly visible to the naked eye, proof: Gitakurakr, who was Illumi disguised with his needles manipulating his facial structure. So, in answer to your question, I kinda doubt you would be able to notice if somebody was being manipulated easily.

3) If the portal hasn't been used, then I'm pretty sure it would be under whatever rubble you're talking about.

4) Why would Zeno need to be concerned about Killua? They believe that Zoldycks can handle anything and with Kilua being the heir, well, that kinda speaks for itself. Plus, I think Zeno saw how much Killua has grown.

5) Well, all of the slots (that we've seen) on Kite's Crazy Slots are all conjured so, no. I don't think it would qualify to be a specialist ability. In order to be a specialist ability, it either has to draw from each of the other categories or be something that doesn't fit into the other categories.

6) Chimera Ant blood is different than Human blood? I don't know. I just wanted to take a stab at this one.

7) No. It's good to question things. It shows that you want to know more about everything.
