Obviously a line has to be drawn somewhere, but if, hypothetically, she is to rejoin, I don't see Christine as the type who would just go in and out as she sees fit. A more likely scenario is that she gives her terms, they work with it and try to compromise, after which she's in for the long haul. What, IMO, is frustrating for many people is how Lindsey saw performing a few more songs on the London shows as her "coming and going"
