I love the support!
But I confess that I cannot imagine that George Martin will allow Tyrion to achieve widespread popularity or acclaimation as a hero. He'll always be despised by the masses. Tyrion must learn to be satisfied to enjoy the love and gratitude of a handful of people... Kevan, Dany, BFS, Jon, Varys, Aegon,
Why would being a Targ necessitate acclamation? The Targs have always been both loved and loathed. Some simply loved (Rhaegar), some simply loathed (Aerys) and some a bit of both (Aegon the Conquerer). Dany would be loved, I think, especially after the nightmare that Cersei has been. Jon would be both loved and loathed. Tyrion will always be Tyrion, and people will hate him just for that. But even he is not entirely without friends. It really depends where the story is going but the dragon must have three heads, and unless Baby Aegis somehow survived and is waiting unbeknownst somewhere, who else is a ripe candidate?
LOL!
I've read people's comments in various threads here that two reasons Tyrion doesn't work as a Targ are:
1) He is undeniably a Lannister
2) Tyrion would mean there are Targ kids popping up all over the place.
I don't believe either to be true, and I will demonstrate.
On Tyrion being too much of a Lannister:
Tyrion was raised by Lannisters in the heart of the Lannister glory, among the most famous Lannisters there are. Certainly this would have an imprint on his behavior. Don't you think Jon growing up among the Stark kids has left the indelible mark of Ned's unflappable sense of honor on him? This is classic nature vs. nurture, and Tyrion was raised to *be* a Lannister. None of that means it's impossible for him to be half a Targaryen. I mean after all, if the theory is correct he is at least *half* Lannister, just as Jon would be half-Stark.
On the notion of "Too Many Targs", I simply call nonsense. Nearly every Lord and King in this series has at least one *******, most have several. Robert had 16 ******* born children. We are theorizing that Jon is one Targ born out of wedlock between 2 people who loved one another and engaged in a consensual relationship, and that Tyrion is a second Targ born out of wedlock due to (presumably) an act of violence or at least coercion. That's two....and two by different fathers to different mothers. Hardly remarkable when you look at the bounty of bastards Robert left littered across the realm, or the numerous bastards that Oberyn has fathered.
Yes, you may argue that why would two major characters both turn out to be ******* Targs, when all of Robert's bastards have only fleeting moments of exposure. Well that's because the story is called the Song of Ice and Fire, not the Song of Storms and Lions. The story begins when the "usurper's" reign is beginning to crumble, and the last known hope of the Targaryen bloodline is reaching an age to do something about getting their birthright back. If there are a couple of extra Targs running around and they are tied to two of the most influential families in the realm, and this story IS about their return to power....well then it doesn't seem strange at all. It would seem strange and cheap if someone we met only once or twice turned out to be a phantom Targ and just turned up with a dragon egg. I think we all would reject that because this story is so elegantly crafted, and everything that's happened has been built on a subtle network of clues along the way.
No, I think Tyrion has to be a dragon.
