Question: when does negan show up on the walking dead

title: The Walking Dead (season 6)
text: Glenn 's fake death in the third episode , `` Thank You '' , was a major source of controversy . The Hollywood Reporter heavily criticized the decision of the writers to create the story line . Daniel Fienberg felt apathetic about the decision and said , `` I 'm not sure I care about ( ... ) the way his death would impact the ensemble . If he 's dead , the loss will be felt most by Maggie , but Maggie just had her sister die a few episodes ago , so there 's no variation anymore to making Lauren Cohan wail , no matter how entirely convincingly she does it . To me , The Walking Dead has lost whatever core of human relationships it ever had , and whether Glenn lives or dies , it just feels mechanical now . '' Tim Goodman expressed shock over the concept of Glenn potentially being alive saying , `` I honestly do n't think showrunner Scott M. Gimple is dumb enough to fake this death somehow , not with how implausible it would be for Glenn to survive it . '' The Hollywood Reporter later declared that the show had `` lost its credibility '' when Glenn was revealed to be alive in the seventh episode , `` Heads Up . '' Scott Gimple responded to the controversy surrounding this . He said , `` We 've had instances of people in a very emotional state -- Tyreese jumping into the middle of a large herd and fighting his way out ; a man cut off his own hand and fights his way through a department store full of walkers . These things are part of the world . Glenn had the bad luck of being knocked off that dumpster by Nicholas , ending his own life but ( Glenn ) had the good luck of Nicholas landing on him . There 's a lot of very specific facts about it that I think a lot of people have sort of gotten wrong . But breaking it down shot for shot ... I think we 're past that point . I do n't think this is any sort of new instance that broke the rules of our show at all . I think it 's very much in line with everything we 've done before . I do n't think there 's a credibility issue . '' Erik Kain for Forbes felt that the decision ruined Glenn 's storyline . He declared season 6 `` a mixed bag '' and was frustrated with the decision to hold off Glenn 's fate for 3 episodes . He said , `` ... the showrunners spent three more episodes essentially refusing to move the plot forward . We got one good backstory , and then two episodes where almost nothing happened to anyone we cared about . We learned that Maggie was pregnant and that 's about all . '' When speaking of the confirmation of Glenn being alive , Kain felt the decision was `` implausible '' from the inconsistency of his fall and camera angle tricks . He also felt the decision to `` ( drag ) it out for weeks '' had `` effectively ( killed ) off all the tension ( ... ) at the end of episode 3 . '' Brian Moylan of The Guardian was also critical , saying : `` Glenn is alive , and The Walking Dead will never be the same ... It would rather kill off a main character than pull a lame switcheroo . Until now . ''
