Spotted...

Quite possibly, nice emerald green-ish Bob Jackson?

I think T4 is the striking, flame haired woman that I let in front of me on Vauxhall bridge this morning, riding up to Victoria in what seemed to be a rather depleted noddy-peloton
I was in uniformis though, inside a vehicular mechanism so did not think it would be very good manners to shout anything pertaining to a request for the locking of a back wheel in order to decrease tyre grip to a critical point.
