DAX: The zhian'tara is a ritual where joined Trills get a chance to actually meet their previous hosts.
KIRA: Meet them? How?
DAX: That's where you come in. If you don't mind, I'd like to borrow your bodies for a few hours.
O'BRIEN: What do you mean borrow our bodies?
DAX: If you agree to participate, the memories of one of my previous hosts will be temporarily removed from the symbiont and imprinted onto you. You essentially become one of my hosts for the duration of the ritual.
BASHIR: And how is this accomplished?
Does Dax now have some of the memories of the temporary hosts, Bashir, Quark, O'Brien, etc.? (I'm not asking about the memories during short time they are bonded, I'm asking about the previous memories of the temporary hosts.)
