Even when Steve and Danny do sleep on the same bed, which is not a very common situation, they never act like some other lovers. They never hold each other in one's arms although they might have more mental intimacy than any time before.
That's not because of the chance of getting caught by Danny's little girl or Steve's mother- ok that's part of the reasons. It's usually like this: they both face their own night stand, with their guns in the drawers. You have to react fast when emergency occurs, which happens quite a lot on this beautiful island.
Dealing with all kinds of danger all day, to survive is such a tricky target.
It's good to know that someone you trust has your back.
So no sweet hugs.
