S2·E2 A Little Tiny Town / The Devious Doppelganger

A) The town is completely empty, only Mona, Charley and Lily are left, but where is everyone else? Peering through a basement window one night, Mona spies Mr. Williams bent over a miniature replica of the town complete with little lights, little cars... and little people!

B) Mona accidentally enters into a mirror and discovers a new world, very similar to ours, but with the difference that good guys are bad and bad guys are good.
