Teddy always tended to be a person of action. He’s less likely to sit on the sidelines and let a decision be made for him. He’s taken steps to move forward and risk where that may lead.
Ryder on the other hand, still has some emotional growing up to do. This may be where Teddy’s troubles will lie with Ryder.
There are also outside influences that may add some turbulence to their path - Liz, Blake, Teddy’s dad, Matt, and maybe even Mike.
Only Ace knows for sure.
