Bigger On The Inside

As the guys speed to the end of Peter Davison's era as The Doctor, both the violence and quality of the series begins to pick up. In "Frontios," despite his reservations, The Doctor comes to the aid of an Earth colony besieged by weaponized meteorite showers. Then in "Resurrection of the Daleks," Davros is freed by his creations because they need him to cure a deadly virus, but it all leads to a Dalek civil war. And the ensuing carnage, bloodshed, and death causes Tegan to flee from her life with The Doctor.
