Remember: Every hour it passes without hints/spoilers it raises Carrot probabilites of joining (remember many leakers are Yamato crybabies who hate Carrot so no spoilers/hints was something I was already counting on).
So, let's do a little math here.
After 1056, Carrot chances of joining were around 35%. It looked like the endgame after being crowned Queen of Zou, though all the clues were still there.
After 1057, Carrot chances raised to 70%. Yamato out of the game was crucial for her to join (we never would've had 2 or more nakama at the same time) and since Yamato went from 100 to 0, it was obvious Oda was gonna do the inverse thing with Carrot.
Now, from that 70%, the fact that we got no spoilers/hints by now should put her chances at 80%.
