This begins a 10 part miniseries, within the last 10 episodes of the 'Mighty Morphin' Power Rangers' 3rd and final season. Streaming service provider, Netflix. Splits these episodes from the rest of the original series. Making the previous episode, "Rangers In Reverse". The last episode, before starting a new series.
It's confirmed that Bulk and Skull knew Billy since they were kids, but they don't remember the other rangers, which makes sense since Tommy, Rocky, Adam, Aisha and Kat hadn't lived in Angel Grove when the series began.
