Curiosity killed the cat but satisfaction brought it back.

[Maybe Steve really is going crazy because Tony is not making sense at all. But if he was crazy wouldn't the others he's spoken to be talking in weird riddles too? All of them had sounded normal so was it just effecting Tony? Another reason the genius shouldn't leave the 'safe' area. It might get worse out in the garden.]

I don't think opening the books to look up what species it was is a good idea. Tony... [He hesitates, not wanting to admit that he might really be slipping mentally, especially when there’s obviously something wrong with Tony.] It looked like... like it was made of spare parts.

[His worries for his sanity fade as he watches Tony. The grin is almost unnerving, unlike the smiles he gives to charm the press or his teammates when they're joking around.]

Tony, stay there. I'll head back. I don't want whatever's out here effecting you.
