Addison Montgomery’s latest stop at Grey Sloan brings a major shake-up in Grey’s Anatomy that quietly rewrites her past. Kate Walsh’s return delivers an emotional update that clashes hard with the hopeful send-off Addison once got on Private Practice. This visit leaves fans questioning whether Addison’s story is truly heading toward a new chapter or circling back home. Amelia swears she’s still on sabbatical, but Addison talks her into just consulting on a pregnant patient with a serious complication. The reveal stings, especially since Jake was supposed to be Addison’s forever after Private Practice.
