My personal theory:
Kaladin never was the "surgeon" mentioned in edgedancer, but Lirin is.
Lirin might have been on his was becoming a radiant, but messed up (stealing the spheres) or deciding against it.
" Curiously, Kaladin’s father just lowered his head and closed his eyes. "
" But you’ve also become one of them"
Also, tbh, young Kaladin didnt seem like someone to draw in an honorspren, but Syl mentioned " “They’re like I remember them.” . Past Lirin would have attracted her more likely than past Kaladin.
