What a great episode! The vultures were definitely swooping and Stan Smart was the "smartest" of the lot. He had $ signs in his eyes, he took what he wanted and left without a trace. I guess that he had had enough of both Colleen and Lance, so starting out a new life was a more prosperous solution with money and a new girl. No wonder he spent most of his time at the Pub and I'm amazed that Colleen really didn't tweak at all - she mustn't have been that cluey when it came to Stan's fascination with the Pub.
I'm glad that Ailsa talked Frank around to being the "insider" in the Macklin Corporation and that he is setting the ground rules.
