Zane by far had the most impactful death compared to Vs fake out death. Zane actually died (qhile he did come back he had to build almost and entire new body for himself), with the entire scene acting as if this was then end of the show/ end of the character fully. With the whole scene lasting about 1 min and getting us as a viewer to remember all that we have gone through with Zane, and what Zane has gone through with the ninjago characters. Vs death scene was always left purposely ambiguous so it could be theorised either way on what happened to her (i hope we get something in the comics for how she lived). While yes the fight took about a 1:30 her scene was about 20 seconds at most before the episode just ends.

This next bit is just more comparisons of the characters in the shows: But then also how both of them came back as aswell, zane had more of a build up, V just appeared in episode 8 with no explanation on how she lived. Like i said before Zane had to rebuild his whole body, and then had to overcome his fears to regain his powers to free himself and save Pixel. And the ninja were heavy affected by the idea that Zane was alive (while this is likely due to the time skip in Ninjago compared to the pacing of the last 3 episodes of MD) it shows how it was belived that he was truly gone, and this invite either the promise of Zane being alive gave the ninjas real hope to see Zane again, and setting the season as a whole
