Trish and Jericho WWE couple was cut short
Trish Stratus revealed she was never actually supposed to turn heel and join forces with Christian. Original plans called for her and Chris Jericho to become a quirky comedic couple nicknamed "Trishtopher", but Vince McMahon changed plans literally just a couple hours before it was supposed to happen at WrestleMania. She then mentions why Christian getting injured was the best thing that happened for her career, because she was no longer the "side piece":
"This is so many months of storyline to get to this moment. We were excited about it. We thought fans wanted this, and they did, and that’s why he changed it. Fans wanted it so bad, he thought no one ever expected me to turn. For me, personally, it was a great moment and I was able to turn.
That was the first change that allowed for something positive...Christian ended up getting injured...I hate to say it, it helped my character because I wasn’t a side piece anymore, I was ‘the one.’ It was basically Jericho vs. Trish Stratus. The guys were fighting on my behalf, maybe Tomko would have a match, but the storyline was Trish and Jericho. It allowed me to grow as a heel, work alongside Jericho, who is amazing and I learned so much working in that capacity. It could have been really good, but I think everything happens for a reason. That was my best work as a heel, and my most enjoyable time, for sure. Who knows what it could have been had Christian continued, but it was what it was, and I think it worked out pretty good."
