Thats a lot unsullied...
Geez did all of them respawned after the battle in Winterfell?share
The Unsullied numbers weren’t too out of line; they said in E4 that about half had survived. The Dothraki appeared to be out of line tho, since they all charged at the walker horde in E3 and only a “few” were supposed to have survived. There were easily in the hundreds left at the victory speech.share
They can't use sexual reproduction, so they reproduce by cuttings. If you plant a foot and you water it, you get a new unsully. That comes in handy after a battle.share
