Trojans

The First Doctor and his companion Vicki paid a visit to Troy during its famous siege. Vicki ended up sticking around, having fallen in love with a local Trojan and presumably turning to face a bucket later that day, the TARDIS long gone at that point, and asking out loud, “I have to sh*t in that?!” Doc meanwhile had picked up an involuntary stowaway in Troy, Katarina, who became his companion until she flushed herself out an airlock.
