Current Problem
So, today our blue tongue skink decided to chill out in a potted plant near the windows for about an hour. This was at ground level about five or six feet from Osiris' cage.
I noticed Osiris was extremely focused on the intruder, colors bright (but not flared up completely) while he kept his nose pointed towards the skink a majority of the time.

After playtime was over for the skink, I collected him to put away, and then noticed that Osiris' colors seemed "off". Lighter than normal, not his pj colors, just sort of faded looking.
Then he seemed almost 'shrunken' a bit later, and was sitting in his basking spot with his eyes closed.
Alarmed, I opened the cage to inspect him, he opened his eyes to look at me, wobbled on his branch, but otherwise didn't move nor really respond (outside of watching me) to my touching him gently (which is HIGHLY irregular for this grump).
I gave him a good hand misting and covered his cage to give him some privacy, but just wondering if it's just a case of too much stress or if there's anything else that might be amiss.

He's recently been treated for a URI, but is in great health otherwise.

I can see why that would be alarming. However, I think it is probably just stress. Staying fired up that long probably wore him down, and closing his eyes under his basking lamp is not a completely uncommon thing to do. Keep a close eye on him, and if problems continue, make another post or reply to this one. The wobbling was probably not unsteadiness, it was more likely him leaf-walking. Chameleons will shake like that to seem like a leaf. My boy does it when hunting, and whenever he feels like I'm being annoying. He may have been going for a camouflage defense, hoping you would think he was a leaf, and that's why he didn't react. Again, just keep an eye on things.

Thanks for the reply.
After giving him a few hours to just kind of chill out in private he seems to have returned to his feisty self.
Since he never seemed to react to the skink before, I wasn't so concerned about their long-distance 'interactions'. But I think now I'm going to have to cover that side of the enclosure when his lizard-neighbor wants some window time for himself.
