[Yukine is hopeful that these changes means thing will go back to normal too. It's not really his powers that he misses, actually, but what they mean. What not having his name implies to him. Either way he has refused to talk too much about it and instead helped Chloe to use some of them. Although without Yato around it's not like he can do much.
He sets out towards the stable bridges to explore and see if everything is changing back. Sure, there's still weird things- that river was not supposed to be there, but it's progress. He can be found near one of those new, random rivers, throwing small stones at it.]
