If it happened it would also have revealed to Felicity that Oliver had known about Connor, which was what happened in the crossover, where Felicity fought with Oliver in the aborted timeline. This could have been the reason why Felicity no longer wears the ring.

I could also kind of see it being Donna Smoak, although taking her away would remove her as Lance's girlfriend, which I think is unlikely, though it would make Felicity emotional.

Otherwise it could be someone to be introduced in future episodes.

The problem with it being her mother is that how sad Oliver and Barry looked. I don't see a reason why they'd be that sad. Oliver has only seen her a few times, and doesn't really "care" "care" for her.

Heck, Barry really doesn't even know she exists. He hasn't seen her once. He cannot be that sad.
