  Summary

  Sonic finally tells his friends about his newfound friendship with Shadow and gets mixed reactions.

  But to tell that story, he also has to tell them how Shadow saved his life, from a certain decision he made to step off of a cliff.

  How will his friends react to the multiple emotional information dumps?

  Oh and of course there's Shadow angst. What would a Sonic-Shadow friendship fic be without Shadow getting angsty and broody? For good reason, though.

  Summary

  The first Shadow POV fic in this series!

  Some members of G.U.N. are trying to seize possession of Shadow, on the claim that he was a G.U.N.-funded experiment. Shadow, obviously, is not impressed. Nor is Team Dark as a whole.

  While all the nonsense with G.U.N. is going on, Shadow is also learning how he fits into the gang now that they all know of the new friendship between Sonic and Shadow.
