[Everything] Fate of Dragons Theory

Potential spoilers, not because I have read spoilers but because in the off chance I'm correct.

I was just going through a death pool with my girlfriend and sister when I had an epiphany. For our death pools, my sister picked Viserion, I picked Rhaegal, and my girlfriend picked Drogon. Now, this got me thinking, is there anyway to decide which dragon is more likely to die? Any hints Martin may have included? Well I decided to look at their names...

Viserion: Viserion was named after Viserys, Dannys brother who died in season one. As we all know, Viserys had an awful temper and was often a loud personality. He was someone you would describe as "all bark, no bite" and was often referred to as "The last dragon", which turned out to be completely wrong.

So what do we know about Viserion that relates him to Viserys other than his name? He is said to have a roar "that would send 100 lions running", and that he is called "the white dragon" although his true color is cream....a muddied version of white....see where I'm going? Viserion is like Viserys in more than just name, he is a dragon with a loud roar and is described as something he isn't actually. I think he may meet an earlier end than we all suspect, probably from Night King (pure speculation)

Drogon: Named after Khal Drogo, a monster of a man and one of the greatest fighters in all the lands...till he was killed by a very minor wound. Never truly living up to all his hype (obligatory Cleganbowl get hype!). Drogon is the biggest of the dragons, the most fierce, and defiantly the one who seems to have the most plot armor out of all the dragons. Most people assume a dragon will die, but few suspect it will be Drogon. I think we are in for a big surprise.

As we saw in the trailers, Drogon will be participating in a large battle taken place on a wide open plane, one where it seems him and the dothraki will be taking on Jamie and the Lannister forces. What else do we see in the trailers? Jamie making what seems to be a last ditch effort charge across a fiery plane with a lance.....well what would he be charging? I'm gonna assume a dragon. What dragon is confirmed to be at those planes? Drogon.

Now for most people, if Jamie were to die in the last ditch effort charge without meeting his intent, it would be a very unfulfilling story ark for him. Especially considering that scene where Jamie looks at the book recording all the deeds of former Lord Commanders of the Kingsguard. Jaimie has almost nothing in there....I believe that is foreshadowing of Jamie having a great accomplishment down the road. Instead of being he Kingslayer, he will be Jamie the Dragonslayer.

That scene of Jamie (both in trailer and with KG book) and the basis of Drogons name, I'm assuming drogon will meet a surprising end.

Finally, Rhaegal: I believe Rhaegal will end up being the surprise leading dragon. His name is based of Rhaegar, the valiant and loved older brother of Danny. Also, there are theories that Rhaegar was the Prince Who Was Promised, where it now seems it was Rhaegars offspring, Jun Snuhhh....what about the Stallion Who Mounts the World? That was supposed to be Danny's son to Drogo, but we know how that turned out...But the dragons are also Danny's "offspring"...

Anyways, there is just some speculation on my part. Feel free to pick it apart or add on! And apologies for sloppy writing, this was all done on my phone
