In her final battle with Marc Antony the blood on Xena's cheek keeps switching sides. First it on her left cheek then on her right cheek. The helm is damaged as well in the early part of the fight (bent on Xena's right side) but is perfect later in the same fight.
Xena must have been a truly remarkable person for not only was she present at the Trojan war, as we have seen in a past episode, but she also had the honor of knowing Cleopatra. Considering that the Trojan war is historically placed at about 1194 BC-1184 BC and the aforementioned historical figure from about 100 BC - 30 BC for Xena to have survived over 1000 years is utterly amazing. Talk about your well kept woman!
