Teach said he was an orphan. Eris is probably LONG dead in present dayI suspect her odds of getting off the island alive are slim.
the lulusia mention makes me think she may because otherwise it'd end up as a random namedrop, though that may mean she's still alive if she was on Sabo's refugee shipNo idea why she wanted to go to Lulusia. Always possible she took Teach there and died of an illness or a broken heart though. Who knows at this point.
