Doctor Who: 216.02 Shadow of the Ice Warriors part two

Trapped in the dungeon, the Doctor’s mind is whirring: how can he stop the Ice Warriors and their nefarious scheme? Teaming up with Viggo, a nobleman kicked out of Gorm’s court for his suspicions, the Doctor must first escape from his cell if he wants to save the day. Assuming he can stay focused for long enough. Freja has been welcomed into Lady Thyra’s retinue and is joining them on the day’s hunt. But with Princess Kasstar tagging along, is the local wildlife their greatest threat? Or is the Princess hiding something dangerous? What hope is a bow and arrow against a sonic blaster?
