Roberto never showed anyone whenever he was low on energy or not feeling at his best. He wanted everyone to see the charming, rich, handsome man he was at all time and he didn't want to show anybody anything else. It was hard, but he refused to let those bad feelings seep out and ruin his image. He hid from everyone, but you.

You were the only one he felt safe enough to actually open up to. When he was with you he could finally just stop putting up the image he has built for himself and just let everything out. He was safe, he was comfortable. He didn't need anything else, he just needed you and then he knew everything would be okay.

After a really long mission the only place that he wants to be right now is at your place, in your arms, in your bed, so he can finally sleep. He lets himself into your apartment and he kicks off his shoes and walks through the hall to try and find you.

When he finds you, you're laying on the couch watching TV. Before you can say or do anything to ask why he is here, he simply lowers himself down on top of you and buries his face in your chest, seeking your comfort. His arms are tight around you, so you can't slip away and he listens to the soft pattern of your heart beating. He was home. He was safe.
