Damned if it ain’t one of the most profound shots I’ve ever seen related to a science-fiction story, one obviously modeled after Leonardo’s “Last Supper.”
For those following the series, the woman in Christ’s place is Six, a cylon in human form (played by Tricia Helfer) who seems to want her newly sentient species and humanity to spiritually merge – which is ironic as hell considering her kin annihilated millions of people on planet Caprica, and have been hounding the last few human survivors across space.
It's also interesting that the only chalice (AKA: holy grail) in the pic is before Lee Adama--whereas in the Leonardo painting there is no cup on the table at all--and that Gaius Baltar (a pure Judas role) is ironically not seated in Judas' spot, but John's - the disciple said to be Christ's most favored.
Whether that is intentional or not is uncertain.
