Corrected entry: Billy tells Tommy that he can use his Portal Opener to rescue Kimberley from the Dark Dimension, where Tommy once was. There are a few mistakes here. 1) The Portal Opener is completely different to one used in Series 1. 2) The first time it was used, it was to go after the Green Candle, which was stealing Tommy's Green Ranger powers. Tommy was never trapped in a Dark Dimension. 3) Kimberely is in Lord Zedd's Dark Dimension, not Rita's. (Which is where the Green Candle was). The Dimensions are completely different.
