Why did Rachels Houndmarks return in X-Men Kingbreaker?
According to Chris Yost, when the Phoenix fragment left Rachel, it left her in the state she was in when it found her (as she was in Days of Future Past). This essentially undoes everything the Phoenix Force did with cleansing her in Excalibur 52. However, it is unclear whether this means that Rachel still has her Hound programming, which would be a major regression. It also hasn’t been explained why Rachel is no longer hiding her Houndmarks, like she used to. Either she doesn’t see the need, or the artists just think she’s cool with them all the time.
