Rebecca Yarros' New Fourth Wing Bonus Scene Might Have Answered The Venin Brother Question
The Bonus Scene Shows Garrick Calling Xaden “Brother”
As theFantasy Fangirls Podcastnotes,Yarros' newFourth Wingbonus scene may have answered the question of who Xaden’s new venin brother is, despite likely taking place before that moment. If we had to guess, the scene is probably set before Xaden rescues Violet from Varrish inIron Flame,though Yarros herself has not confirmed which chapter it’s covering just yet.
Garrick and Xaden are preparing to go hunt wyvern, with Garrick referring to Xaden as “brother"before expressing his concerns about how this will affect their primary mission. That reference only adds to the mystery ofOnyx Storm’s venin brother question, especially for those convinced that it isGarrick who turned at the endof the thirdEmpyreanbook.

As a result, manyFourth Wingtheories have cropped up regarding this new bonus scene, as it could reveal more about the future plot despite taking place in a previous book. These new theories have only complicated the question in the best ways, making the wait and mystery all the more interesting for fans.
How This Fourth Wing Bonus Scene Complicates Who The Venin Brother Could Be
The “New Part” Could Refer To Venin Status Or A New Moniker
TheFourth Wingbonus scene could confirm Garrick as the new venin brother, or it could take him out of the running, giving readers plenty to discuss. On the one hand,seeing Garrick refer to Xaden as “brother” earlier could mean that Garrick is not the one Xaden refers to as his “new brother"inOnyx Storm. After all, Xaden already considers him one.
If they already consider each other to be brothers,then Xaden referring to Garrick in this way would make no sense,taking Garrick out of the running for thisFourth Wingmystery. Bodhi, though, is still fair game; Xaden refers to him as family, but the brother moniker could be a symbol of a newer, darker connection.
However,Xaden’s use of “new” could simply be in reference to the person’s venin status, changing the meaning and putting Garrick back in the running. Either way, thisFourth Wingbonus scene only makes this mystery more enticing and will likely make its final reveal all the more interesting when book 4 finally arrives.
