A princess named Daisy has come through a time rift from the 16th century and finds herself at Cyd and Shelby’s school. (source: imdb.com)

Our intrepid foursome is back for another season. At the end of last season, Cyd and Shelby vanquished enemy Janet Smythe. But at the tail end of the episode, a rift opened between another time and the present and a shadowy figure emerged.
It turns out that figure is Daisy, a medieval princess who has been locked in a room whose door never opens and who has food slid under the door. Now, here’s my pet peeve. You just traveled into the future about 600 years. It seems like you’d want a little bit more detail about what the heck is going on. Princess Daisy seems pretty content with her new surroundings.
Budding scientist Barry is seeking his “moment” to recreate time travel in his RV lab. It clearly still irks Barry that Cyd and Shelby “discovered” time travel (by zapping Naldo’s hair gel). Barry tries every trick in his lab book to recreate it but to no avail. His last attempt, some concoction made to resemble Barry’s hair gel, basically explodes the RV. And in probably the quickest rebuild ever (Hilary from Love It Or List It would be proud), Barry’s parents build him a state of the art new lab in a state of the art garage (that has the same furniture arrangement as I Didn’t Do It). Interesting the social area is front and center; the lab is in the back. I still haven’t figured out how Barry’s RV or now the garage is in Shelby’s backyard.
Cyd and Shelby decide to help send Princess Daisy back to her time – and just stand around the high school lobby area waiting for a rift to appear. I guess there’s no way of checking that it’s the right rift to the right time. After they hear Daisy’s tale of woe, they decide to save her from the rift.
There’s a funky little subplot about Mr. Doyle (dishy Doyle, loves the hot goss), using the chem lab as a place to stay since his mom kicked him out. Please stop making teachers idiots.
So Princess Daisy acclimates to her new lifestyle pretty quickly. Naldo’s mom allows her to stay at his house (I wonder how he explained that one!) My bet is that Princess Daisy is somehow related to Janet Smythe.
