X-23 potentially will be appearing in Black Widow's December 2014's issue 11. At least she's shown to be on the cover of it.
So if All-New X-Men's characterization of X-23 doesn't feel accurate enough for you, here's potentially a throwback to an X-23 that may feel more in character. It may even continue on to grow this friendship as previously shown in the pages of the Marjorie Liu run of X-23 v3 in the final issue.
Special thanks to Phil Noto for the heads up via his Tumblr with the cover he drew.
