I think R'hllorism is just Valyrian fire magic, that got infected by religious dogma shortly before, or after, The Doom. Moreover, I think the word R'hllor is a bastarded version of the Valyrian name "Rhaellor." We don't see this directly as a name in the series, but it fits the construction of Valyrian Names, in that all of the syllables line up with syllables from existing Targaryens from Westeros. Rhaegar, Maegor, Baelor, Aegor, etc. The shift to R'hloor is explained with linguistic drift over hundreds of years. Especially since the vowel "ae" seems to be mostly unique to the Valyrian language, it would make sense that people speaking other languages, using the word, would just shift to a vowel normal in their language, thus turning "Rhaellor" into "R'hllor." My guess would be that Rhaellor was a central figure/prophet for the religion, like Buddha or Jesus, thus getting the religion named after him.

This isn't a thoroughly researched theory, but I think Young Griff may have some connection to Princess Saera Targaryen, the child of Jaehaerys Targaryen & Queen Alysanne. Saera was the willful child who ended up being disowned by her family, because of her sins. When she was caught she tried to steal a dragon and escape, but failed. Jaehaerys then gave Saera to the Faith, sending her to Oldtown to be trained by her sister, Septa Maegelle. But she escaped from Oldtown, and started working in a Lysene pleasure house, still dressed as a novice of the faith. The main connection that seems odd to me is that Ilyrio's second wife, who he found in a Lysene pleasure house, was named Serra. I know George likes to recycle concepts, and names, but only the spelling & time period have changed. To be clear, I'm not saying Ilyrio's Serra and Princess Saera are the same person. Just that it seems an odd coincidence that perhaps hints at something.

I think he believes the official narrative, it's not clear if Tywin even knows the real story. Tywin tells Tyrion that the Ironmen sacked Winterfell. When Jaime returns Tywin doesn't mention the sack of Winterfell one way or another, and he doesn't seem to know much about the Boltons and their involvement. He comments that he heard about Jaime's "escape" through Varys, but then confusingly also says Lord Bolton made it seem like Jaime would have been back in time for the wedding. I don't think Tywin cared much, one way or another. He wasn't like to look too deeply into it, one way or another.

Is there any meaningful connection between Illyrio's Serra, who worked at a Lysene pillow house, and Saera Targaryen, who took service at a Lysene pleasure house? I know they're not the same people, because they lived several hundred years apart from each other, and they had different eye and hair colors. But the idea that Serra was Saera's descendent, or somehow named after her seems unlikely. Is it just a weird coincidence?
