Shea is Travis' only human friend, really, and the solidarity is nice. But beyond that, they actually do get along great. Travis has a sneaking suspicion that he's a bit too boring for Shea's nosy, thrill-seeking tastes, but he doesn't take it personally or anything. It's nice to wind down and commiserate with a fellow human!
Travis is one of Shea's friends. Shea works a lot harder than Travis ever seems to, so he doesn't get to spend too much time with his buddy, but he's glad to keep in touch with the guy. It's actually pretty hard to find someone as down-to-earth and, well, humble, as Travis, in this universe. Yeah, he is a bit boring, but it comes with the territory of being a young coddled human. Shea is the whole reason Travis was able to meet one of his great-great-great-aunt's creations, an Android named Node.
"What would a guy like me have for a guy like him?" Travis... Just sayin', but you're sitting on a goldmine of information having an android like Node be part of your 'family'.... Beside the gritty details and the almost pathetic level of miscommunication these two are on, Travis thinks Rex is very suave and cool, and LOVES spending time with him. He makes life exciting! Don't get the kid started on how Rex glows, how he's SUPER warm (oh that touch, whew), and how he drops hints that he's like, a super spy or something.
Having read up on Travis, maybe Rex feels just a little out of the loop in wondering why the boy won't spill the beans ASAP on his 'droid. Then again, Rex already knows quite a bit about Node. ...This ol' plasma isn't nearly as suave as he'd hope when it comes to the scrawny apple of his eye.
Node is a spooky android that is apparently one of Travis' great, great, great-Aunt's creations. He didn't even know he had one of those! Regardless, it's hard to take the tall 'droid seriously. He's very dull and old-looking, and does not seem to be the bodyguard he said he once was. He's already kind of annoying, and acts like another parental figure, as if Travis didn't have too many as it is. But deep down, the young man is interested in his seemingly strong connection to this 'droid, and his family's past come back to life.
The feeling to protect was dusted off from his servos: his master's DNA screamed across his sensors when he barely saw a sliver of Travis' skin-- Node knew he was screwed. He knew he'd never be able to shake the feeling of needing to keep Travis safe; the feeling is probably similar to something like a father and child, but what does an android know about those kinds of things, right?
