Tim, Rogue Wave still has some sort of ejector seat strapped to his bum since the war years (something to do with the presence of a sniper in his back garden).
He has used this successfully on his own Scorpion, our Gemini and various other craft (ask Breeze Block
).
He tried it out on Merlin but Paul had cleverly wedged him on the front seat .
Thereby only an expensive crown was ejected from the shy and retiring gentleman's mouth
It has been replaced with garnet and rhinestones from the Edwardian era. (á la Johnny Depp).
The common denominator in twitchiness may indeed be the inimitable (and incomparable) Rogue Wave himself
