Unconfirmed, but interviews point us at Gradys son Gadren.
Brandon, I would love to know if we finally found out who Gaidal Cain was reborn as (or had a brief mention of him) in Towers of Midnight? I really thought it was obvious, but after talking to >some friends I guess it wasn't. I realize you might not be able to say who it is, but if you could just let me know if we did hear mention of him in Towers of Midnight, that would be awesome.
I know what you're talking about. I won't confirm 100% or not, but the phrasing was intentional.
This is apparently in reference to Grady's son, who was (by Rand's estimate) four years old in Lord of Chaos and therefore too old to be Gaidal Cain (unless Grady has another son and didn't >bother to mention the other to Rand, which seems unlikely).
Is Gaidal Cain, Grady's kid, Gadren?
BRANDON SANDERSON (23 JANUARY 2013)
That's a good theory. Some fans think he would be too old, however. What do you think?
I have a question about who Gaidal and Birgitte might be reborn as. I was wondering if Gaidal could be the son of an Asha'man and if Birgitte might be reborn as an Aiel?
Gaidal definitely could be, and there's a pretty big hint in Towers of Midnight that many folks online have found. As for Birgitte, it's possible.interviews staken from Theoryland
Towers of Midnight quote in question.
I’m sure he’s a handsome child, Grady.” Grady laughed. It felt odd, but good, to hear that from the man. “Handsome? Gadren? No, my Lord, he might be big for his age, but he’s about as pretty as a stump.
The biggest issue with Gadren is that Rand claims hes 4 years old, however, Sanderson seems to add a line here to handwave that away.
he might be big for his age
This appears to be an easy way to ignore Rands previous comment and have the timelines fit better.
The issue with the timeline is that Gaidal should be about ~ 1 in Lord of Chaos yet Rand thinks Gradys child is 4, However, the child is never named and we dont know how many children Grady has, but about 2 years later when Grady is talking to Perrin I get the impression his child is still fairly young and probably aged around 3-4 which would better fit into the timeline we want.
This can be explained a few ways
Sanderson was not aware of the previous quote by Rand that Gradys son was 4 when writing this part of the novel. Which is completely understandable when finishing someone elses series that has 10 published books already.
Grady has a second son that fits the timeline and was just not present when Rand visited the farm.
Rand really needs to learn how to age children.
Gadren is not Gaidel Cain.
Upon further digging, Sanderson also claims that Grady has multiple children, which fits option 2 above, and would solve our timeline issues.
TEREZ Okay, so, Grady has multiple children.... (pauses for
BRANDON SANDERSON (gets this gleefully smug look on his face that
knocks about a quarter century off his age)
TEREZ What is that look for? I mean, come on. You've been, like,
dancing around the bush...(crosstalk)
BRANDON SANDERSON I've dodged this one so well, Terez! (crosstalk)
TEREZ ...on this one for like two years, I'm not gonna let you dodge
any more! Just tell me if he has multiple children.
BRANDON SANDERSON (stubbornly reluctant) Grady. Has. Multiple.
TEREZ Thank you. (Someone is laughing, I don't know who.)
