Why?
This is first a wonderfully detailed exploration of what it means to be a Time Agent. Jack shows to Ianto how to use his "Temporal Hyper-acuity". Even though the story is set at some point between Cyberwoman and Countrycide, and features a Ianto that still hates Jack and resents him, Ianto is able to ignore his feelings to be fascinated by the new world Jack is helping him discover.
I like detailed descriptions of original concepts (magic in HP, and science in DW/TW) and this story certainly delivers.
