Ambassador of Thrace

The Ambassador of Thrace hosted a party attended by the Lady Cassandra O'Brien. Cassandra particularly remembered the party as the last time someone told her she was beautiful. Unknown to her at the time, this person was actually a future, dying version of herself in Chip's body, brought to revisit her past in her last moments by the Tenth Doctor and Rose Tyler. Cassandra died in her past self's arms at the party. (TV: New Earth)
