Abras practices a lot. There are so many things worth learning available, Farsight and Fetching and what little Healing he's capable of, keeping multiple pieces of magic going at once, doing things with his eyes closed or in the saddle or both. The more his physical and magical stamina increase the more of each day he can spend keeping himself too busy to think--about Tylendel, about his eventual return to Haven and its memories and a set of responsibilities he still hasn't quite mapped the edges of.
He agrees to every scouting mission he's invited on. They're better practice than practice, and more distracting, and he does keep managing to avoid making things go worse than if he hadn't been there, but the real reason is that if he ever said no he wouldn't trust his own motives for saying it.
He's always loved midwinter, as a time of year when the ordinary cycles of things pause and everyone turns from whatever they were doing to focus hard on enjoying themselves. This is the first time he's ever cared about his performance in a snowball fight; his aim with thrown projectiles is still terrible but he does at one point manage to Fetch a snowball into Moondance's stomach shortly before getting pasted himself.
