Wolfsbane, aka Rahne Sinclair, appeared in the original 1990s run of X-Factor as well as the 2005 revival, but left the team in 2008 to join X-Force.
However, Wolfsbane recently left X-Force in issue #25, opening the door to the possibility of a return to X-Factor.
When asked by CBR as to whether her reappearance in the title will be temporary or permanent, David replied: "I'll keep her around for as long as [Marvel] let me."
He teased that the character will learn what has been happening recently in X-Factor and that he will be exploring her reaction to being reunited with former romantic interest Rictor, who is currently in a homosexual relationship with another member of the team.
Wolfsbane will return in X-Factor #208, which is to be released on August 18.
