In addition to @Elegy I can actually only add this WOB: So, apparently the measurements are x1.06. Hence, when Kaladin is around 6'8", then Shallan might be 5'9" on earth. Rock - who is described as almost 7 feet tall - is probably as tall as a small Koloss!

I do think Sigzil is more secretive than most in Bridge Four. After all, Kaladin managed to hear the past from most bridgemen but definitely not from Sigzil - who still shuts down every time when asked about his past or a certain white haired man is mentioned. But surely, not every Truthwatcher will be" secretive" in nature. The Orders must have a much wider range of personalities with their growing number of members. Personally, I don't think Elsecaller would be a good fit as their second attribute is Careful and they seek Self-Mastery. I'd rather want to see him become a better mediator. But then again, I might be a bit biased here... Although, he could also make a good Skybreaker. He surely is focused on his paper work...

Honestly, I thought about this before, although my guess has always been on Sigzil. Sigzil could work very well as a Truthwatcher. Especially as a Worldsinger the Truthwatcher attributes "Learned/ Giving" seem such a perfect fit. He is very secretive, educative and factual, which are traits often associated to the members of the Order of the Truthwatchers, but when trying to convey his ideas and knowledge he still needs a lot of improvement (e.g. that one time he tried - and utterly failed - to explain Kaladin the story of Mishim). Therefore, I noticed that bonding a Truthwatcher spren could work very well for his own development. And with that being said, I would just really appreciate it to see more healers in Bridge Four - Renarin can't remain the only one!

Honestly, I didn't expect such a definite result! I also assumed I'd be much more of an Edgedancer... Well, close enough.
