Jimmy meets Siobhan's father David and they go to dinner with Diana. Diana and David seem to hit it off and start dating but she feels smothered by the gifts - including a giant teddy bear - that he sends her and asks Jimmy to break things off for her, Unfortunately Jimmy leads David to believe he is breaking with Siobhan and it is left to Diana to brutally dump David,who is not at all concerned. Alex's family tree of what would happen if David and Diana married is thus redundant.
