#1 The Undertaker is struggling with his retirement decision

The one recurring theme across all the three chapters of The Last Ride so far has been the retirement of The Undertaker. However, instead of Mark Calaway giving us an idea of when he could possibly hang up his boots, we've seen him being confused about the decision. Towards the end of the second chapter, this is what The Undertaker had to say:
"You know it's been a running joke - in how many years I'm gonna retire. I think if I had to I could, it's just a matter of if I want to. I could look at it like, okay you can still go, now do you wanna go? There's no sense in giving you an answer really 'cause I couldn't give you an honest one."

In the third chapter of the series, we saw The Undertaker talking about Shawn Michaels walking into the Streak vs Career match at WrestleMania 26 knowing that this was the end of the line for him. He stated that he also wanted that kind of clarity.
“I’m so envious of Shawn because he was able to walk away from it, he was good with it. Do I wish I had that clarity? Absolutely. I absolutely wish I had that clarity.”
It only goes on to show that The Deadman is struggling to come to terms with his retirement decision.
