I remember liking the Romeo and Juliet references when I first watched the episode but I hated Tony and Maria so darn much!
I found them annoying, especially with those va va va, ni, ni, ni sounds they made and I was practically begging for them to die by the end of the episode. Unfortunately, this never happened because that's Pokemon we're talking about
But if I was the one writing the episode I would have Maria and Tony run away from their trainers so that they can be together.
They would find refuge in a forest.
They would be very happy...
And then...
A wild Persian would appear and start chasing the Nidoran. Tony would stand in front of Maria to defend her but then the Persian would knock him out with Power Gem and slash at his stomach.
His innards would fly out and his blood would splash all over Maria's face who would be too horrified to even move. The Persian would approach the disemboweled Nidoran, grab its innards, pull them out of its body and start eating them. Tony would squeal in agony and ask Maria for help but she would be petrified. Then, Persian would grab Nidoran in its jaws and run away with its prey, leaving Maria all alone to register what happened.
After realizing that Tony was gone, Maria would start mourning. Her cries would be heard all over the forest attracting the interest of a pack of Growlithe. They would start chasing her, corner her against a cliff and tear her apart within seconds. After the Growlithe finish their meal, the only thing that would be left from Maria would be a pile of bloody bones and her bow.
Now, that's the end those two disgusting rodents deserved
