Note that we don't know how much time has passed during the events of ARR, HW, SB, and the events on the Source in ShB (note that the Scions who were taken to the First are basically corporeal spirits there, they don't age). All we know is that between the end of Legacy and the start of ARR 5 years had passed. As for Thancred's more mature look in HW and SB, it is possible that it was simply retconned in ShB, as he is back to his ARR look in ShB (even when he and the rest of the Scions are returned to their bodies in the Source).
