We'll have wait until later; right now, we're stuck in a time-loop.
Panel 1: We start off with Elly on the phone; she tells her mother that she is indeed going to potty-train Lizzie but she doesn't seem to be ready yet.
Panel 2: She then goes on to say that while she does have a potty, Lizzie refuses to sit on it. She then tells YesMOTHER it's a regular one of the regular size.
Panel 3: As she bears witness to Lizzie wearing the thing like a hat, she tells Marian it's actually a perfect fit.
Summary: The reprint last appeared on 13 February 2008; this tells me that Lynn is so confident that her readers have the attention span of a goldfish, she can mine strips from the Hybrid era.
