Bliss ( The Starship of Theseus ) Bliss was a companion of the Eighth Doctor . They met onboard the " Theseus " . Early life . Through biodata analysis , Bliss ' ancestry was traced to the South Asia subcontinent on Earth . ( AUDIO : " The Conscript " ) She was an alumna of Luna University . ( AUDIO : " Echoes of War " ) Caught up in the Time War . When a Time Lord agent crashed onboard the " Theseus " , it allowed the Dalek s to enter the ship in search for the Time Lords . Once onboard , they went on to kill all passengers and crew . Bliss was part of a group of survivors that the Doctor rounded up in order to escape via his TARDIS . However , the TARDIS was not where the Doctor had landed it , so he led them back to a Dalek ship which had been left by them . ( AUDIO : " The Starship of Theseus " ) The Doctor tried to escape , but the ship was badly damaged and it fell down to the planet below . This planet was a jungle planet , yet fallout from the Time War badly affected it and it went through constant states of flux , with the jungle dying , and then growing back again over and over again . The Dalek ship was not empty as the group had thought , with it containing a Dalek who had lost its memory and therefore did not display normal Dalek personality traits . The Doctor quickly christened this Dalek ; Dal in order for it to not discover its true species name , the possibility of it remembering what it is was too risky . Dal discovered a temporal safe zone , and so began to lead the group on its way there . However , on the way , the group were attacked by primate - like creatures , and the Doctor was amongst those taken . Due to this , Dal elected Bliss as the new group leader , and they continued to press onwards to the safe zone . On arrival at the zone , the group found those who had been taken there . They discovered the creatures were benign , they had simply been affected by the fallout of the War and were trying to ask for help . The Doctor found that the TARDIS had been damaged by the fallout , and so in an attempt at healing itself , it prevented all access to the console room . At this time , numerous TARDIS es arrived in the zone , Cardinal Ollistra being a part of the group of Time Lords having just landed . Dal was destroyed , despite the Doctor ' s effects and Bliss , with the rest of the survivors were taken via TARDIS to a nearby Gallifreyan Military Moon Base . ( AUDIO : " Echoes of War " ) Held at the Gallifreyan base , Bliss was interrogated by Ollistra whilst the Doctor was being trained to fight in the war . After Daleks began to attack the base , she met up with the Doctor , Rupa and Quarren , and was present when Ollistra threated to shoot the Doctor once they had gotten to his TARDIS . ( AUDIO : " The Conscript " ) Ollistra did not shoot the Doctor and instead asked for a way out of the base . The Doctor tried to leave the system , but he could not do anything until he left the boundaries of the system . The Dalek ships tried to block the TARDIS , by materialising in the same point in space across all time , preventing the TARDIS access out of the system . Bliss then pointed out the quantum theory that if the Dalek ship is simultaneously everywhere , then it ' s also nowhere . Trusting her , the Doctor continued the path the TARDIS was taking and passed right through the ships . Ollistra then revealed the truth about Quarren , he was actually a Time Lord who made himself human because of his psychic powers . After Quarren turned himself back to human and before he wiped himself from history , he set in motion events to make Bliss the Doctor ' s companion . ( AUDIO : " One Life " )
