I'm glad that I can fill that line for you, then! :D Eli's a hard worker who has done everything that he can to prove himself better than his upbringing/his family. So even though Nate's in town, he works really hard to set himself apart from him. He probably tries really hard to get Anabel to like him without being overbearing. And he offers to do extra work/goes above and beyond to be the best tech possible for Gregory.
Depending on how long Gregory has been the vet in Fall City, Eli used to rescue close-to-dying animals (you know, when a bird hits a window or a nest falls to the ground, or an accidentally-hit-but-somehow-still-alive squirrel) and take them to the vet. (As a direct parallel to Nate, to show they're different, but also as a correlation into why Eli got into being into helping animals as a vet tech.) So Gregory might have known him growing up in that capacity, too.
Also, Eli's pretty much the best with Megan, but he'd take any chiding/joking remarks about treating her well very seriously.
Okay, back to Ty.
Tony's going to have a lot of fun with Ty, I think. Because Ty's a few crayons short of a box. So Ty's a tag-along, in that if someone invited him to do something, he'd go. But he also somehow finds trouble on his own. It just kind of...happens to him. So he'll need all the help he can get.
I should figure out who Harrison is. But yes--let's see how that goes. But Ty's still happy to unintentionally destroy things.
Gregory will see lots of Ty with dogs. :) Plus his own dog.
