Question: I hope you can help me settle a bet with my husband. Tonight we were watching Law &#038 Order reruns on TNT. The episode "Mushrooms," from Feb. 26, 1991 aired. I noticed that the part of the children's mother was being played by S. Epatha Merkerson, who now plays Lt. Van Buren. My husband said it wasn't her. We tried to check the credits at the end, but they ran by too quickly. Just wondering if you can find out if she did appear in that episode or point me to a place where I can find out. Thanks! — Jeannie

Televisionary: Now, why would I send you clicking off into oblivion when all your answers are right here, Jeannie? Don't you know your devoted knower-of-all-things-TV better than that?

Ms. Merkerson did indeed appear in that Season-One episode before returning to the show 10 seasons ago to play, as you say, Lt. Anita Van Buren.

You also may remember her as Reba the Mail Lady on the brilliant Pee-Wee's Playhouse or recall her starring role in Mann &#038 Machine or her appearances on The Cosby Show and Equal Justice. On the big screen, the actress has appeared in such films as Terminator II: Judgment Day, Random Hearts and Jacob's Ladder.
