Didn’t his sword get melted to make the lannister ones? At the start of the episode after red wedding?
Makes sense. The timing of it made me assume it was Rob’s sword, because it was just after the red wedding.
Normally I would rewatch and keep a close look for the details here, but… I’ll take your word for it
If you need a refresher, after Ned Stark gets executed, Tywin got Tobho Mott to melt down Ice into two swords. He gave one to Jamie called Oathkeep while the other one gave to Joffrey call Widow’s Wail (he was really a piece of shit). Joffrey uses that sword to cut the pies during the purple wedding and stuff.
