I think this might be the right board to post this in. In the last season of Sister Sister in the last Espoide, Lisa (also played by Jackee) is in the store. And the salesperson says, Are you Sandra? And she replies no, then someone else asks that. I think that it was cute that they asked that. I wonder if that was suppose to be some sort of a story there from 227 why they brought it into Sister Sister. Or if they just did it because they wanted to. :)

There were no related issues with the two shows. Then "Sandra" thing was just added for laughs and irony. That's all.
