These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
For Want of a Nail: HOLY CRAP, her decision to hire Brad Maddox as a referee during her GM tenure seemed so insignificant at the time. Until you think about how things could have gone company-wide if Maddox wasn't hired.
With no Maddox nut-punch to Ryback, Ryback becomes the WWE Champion in August 2012, ending CM Punk's title reign three months early and taking a huge bite out of his career bragging rights by cutting him off at 343 consecutive days, not 434. It's also possible that with no title to defend, Paul Heyman never makes the call to a certain trio of black-clad vigilantes, drastically altering their story arc as well. And given Ryback's Badass Decay only happened after his issues with the Shield, who knows how long Ryback would have held the title... which might have done some serious card-scrambling at the Royal Rumble, where we could have had a returning Rock against Ryback or someone else entirely as opposed to punk.
As for Maddox himself, he stays in NXT, doesn't get noticed by the Mc Mahons, and doesn't become AJ Lee's successor as GM. note Vickie Guerrero was the de facto GM after AJ resigned, but Brad Maddox was the next to actually hold the true and permanent title.
Les Yay: With Kaitlyn, to preposterous degrees (witness the 3/29/13 mixed tag match). Also with Tamina, Eve, Layla, and Natalya. Most everybody.
In a Tweet after her confrontation with Stephanie McMahon backstage on the 9/23/13 RAW:
@WWEAJLee: When Boss Lady talked about finding love then moved in close to my face, I thought that entry in my dream journal was about to come true.
Being ascended fans that plied their craft in the indies (all three)
Lacking prototypical size for a WWE wrestler (all three)
Spending a good amount of time in a gimmick of having mental issues (Punk, too... remember the Straight Edge Society?)
Shot to the top of their respective parts of the company around the time of a blistering Worked Shoot promo that was supposed to be heelish in nature but got them over with the fans (mainly AJ and Punk)
Became known for an Animal Motif submission finisher (AJ with the Black Widow, Punk with the Anaconda Vise)
Fridge Logic: Turned on John Cena to join Dolph Ziggler, claiming that Cena had toyed with her emotions and broke her heart when he was unwilling to let her join him at ringside for a match...but Ziggler had insulted her so much she attacked him in the locker room. Then again, this is AJ we're talking about.
Fridge Brilliance: She hooked up withh Ziggler precisely because of what he did that night. Number one, the part about making someone her entire world over the tiniest sliver of attention had to have struck a nerve for a reason—maybe Cena didn't love her back anymore than Daniel Bryan, Kane, or CM Punk ever did. From there, she was bound to perceive Cena's continued hot-and-cold way of dealing with her as toying with her heart and thus turn against him for it, as even to the sane it seemed as if he was getting her hopes up while keeping her at arm's length romantically. With that being the case, in that one moment of telling her off Dolph was more honest with her than any guy she'd tried to be with (or vice versa)—and he did it all without calling her crazy. It stands to "reason", for lack of a better term, that in her mind he would be the most real and passionate romantic partner she could have in WWE. And so far it's worked out so well she currently has the most foundation she's had mentally since Bryan dumped herů
That headscratcher is no longer a problem. In fact, none of this is even a thing anymore. Between Ziggler and Alberto Del Rio's Face Heel Double Turn, along with AJ and Big E becoming more focused on torturing Kaitlyn together, she and Dolph gradually grew distant as a couple until she cost Dolph a world championship rematch and he decided he'd had enough. As a result, AJ has currently gone full-on bazonkas with her no-longer-requited love for Dolph and arguably Kaitlyn.
Moral Event Horizon: Crossed it when she was revealed to be behind Kaitlyn's secret admirer. Previously she had only snapped when people called her crazy and had a few violent fights backstage. Here however she crossed the line into outright Manipulative Bitch and solidified herself as genuine evil.
The Scrappy: Her onscreen romances with CM Punk, Daniel Bryan, and Kane were not too well-received in some circles on the internet, mainly due to the segment in which she put both Punk and Bryan through tables, effectively going over both the WWE Champion and the number one contender in less than a minute. Her stint as the Raw GM immediately following the previously mentioned angle was even less well-received. She seems to have gotten better since her Face-Heel Turn and alliance with Dolph Ziggler, though. As stated above, all this means she has a pretty sizable Broken Base, which doesn't exactly hurt when it comes to being a heel.
