THE DOCTOR was lost in thought, his brow deeply furrowed in a contemplative frown as he walked behind the trio of Viyrans through the corridors of their command ship. Riddell and Flo followed behind him, congratulating one another noisily on how they had saved the mighty Shadow Proclamation from the devastation that the errant Starmind had threatened, replaying their roles with ever more exaggeration and aggrandisement.
Suddenly, the Doctor stopped in his tracks, whirled around and glared at them both. One wordless stare from his piercing eyes was enough to bring a sudden halt to their conversation. Usually the most effervescent person in the room, the Doctor’s moments of seriousness were all the more intense for their comparative rarity. His point made and his travelling companions silenced, he resumed his march in deep thought. Riddell and Flo exchanged glances like a couple of rebuked schoolchildren, shrugged, and then followed behind him in cowed silence. The Viyrans had led them all the way back to the waiting TARDIS before Riddell first summoned the courage to speak again, seeking the break the tension.
