In ''Move - And You're Dead", after Alan has been rescued from an explosive bridge, Virgil plays a prank on him by having him pose for a portrait and secretly painting him in a comical Picasso style. After getting his revenge, Alan contemplates the picture:
Alan: "How d'ya like that, Tin-Tin?"
Tin-Tin: Never mind, Alan. Who needs a painting? Especially when we've got the real thing."
In Thunderbirds Are Go:
Lady Penelope: "Remember Alan, one of the most comforting feelings a man can have in this world of ours, is never to be alone."
Also, afterwards when Jeff toasts "To Alan, the hero of the day!"
The 2004 live action film has this exchange:
Gordon: Come on, Dad. The situation's hopeless.
Jeff: No, it's not. We've got people on the ground working for us.
