☆Outside and free of the Institute and traveling with Sole, whenever X6 finds some small children's clothes, he will gather and store them for later. After returning home, he'll get some tools and turn them into clothes for the cats around the settlement. I mean, he turns plenty of it into useful stuff, of course, but he has to keep his cats warm.
☆While X6 was a part of the Institute, he never relaxed, or even allowed to relax. His thoughts aligned with the Institute in that he's a synth, and they don't need to have that luxury. When Sole came around, Sole encouraged X6-88 to take his time and look around not just to watch out for enemies but to take in the beauty of the land and sounds of the sea. Sole wanted him to live. X6, of course, thought this was unnecessary but tried when both Shaun and Sole started hounding him. First, he started with the sea. Looking at the water bored him, but the sounds of the waves crashing and flowing is what got him. It felt nice.
☆He's never been someone who's interested in hats or odd outfits, never really liked them. But young Shaun does. Shaun likes wearing funky, weird clothes and hats. Shaun always asked for X6 to dress up with.
"We can be cowboys, X6! It'd be so cool!" X6 would finally relent and, for Shaun and Shaun only, does put a hat on. But that's it, just a hat. Well, maybe a coat or a vest. Fine, and a superhero mask. That's where he draws a line.
