In the past whenever Yukine was grieving he stung Yato. Right now after learning bits about his past he went into despair yet again but by the looks of it he hasn't stung father yet. It could also be that his emotional state is not yet at the level where he could blight himself and his master or is it one of the side effects of being named by Koto no ha? He could still sting Yato but not the trash dad because he named him with the brush? Oh Yeah, how could I forget, That was the very reason Ebisu went to the underworld so he could name ayakashi without getting blighted.
