2005, Ed Lake remarked:
Then he only had to carry 10 pounds on this walk or ride to Euston
(Square?) Station to place the bag with the final bomb on the upper
deck of the bus heading back to King's Cross.

The bus was headed the other way, and there's a 45 minute gap. Why would
he want to go back to Euston (Sq) having left the last bomb on the
Piccadilly, anyway? That means he was retracing his steps to the scene
of the earlier crime (the planting of the two Circle Line bombs).

If he wanted to plant a bomb on a bus there are plenty of them passing
right outside Kings Cross. But that still doesn't explain the 45
minutes.

The theory I heard was he picked that bus because it would arrive at
KXSP and go off while people were exiting the station. However, the bus
was detoured so it went off on a side street.
