Jyn Erso/Sara Lance?
The first time Jyn meets Sara, she doesn’t even notice her in the crowd. (Sara notices her. For Sara, this is the second time sees Jyn.)
The second time they’re both running from Stormtroopers and running in the same direction, it makes sense to have another’s back, right?
It isn’t until the third time, in a cantina, that she learns Sara’s name. Sara buys her a drink which she doesn’t get to drink - they’re running again, this time from a group of pirates chasing only after Sara. Jyn is kind of impressed that Sara has more people hunting her than she does. They part ways with Sara giving her a kiss for good luck and “next time, you’re buying”
When the Rebel Alliance rescues Jyn from Wobani, they are the second ones to do so.
