Stabbing on a bike.

I am led to believe that being stabbed feels like being kicked. A wound that causes blood to enter the mouth means penetration of gut or lung. Either can be serious to the point of being fatal, loss of consciousness means a large to massive bleed.

The narrative of this story is first person - unconscious/dying/dead people don't tend to say very much.

The number of the episode is significant.

Angharad.
