Originally aired during season 5, this episode actually occurs after the Phoenix Saga adaptation during Season 3. The service held for Jean at the beginning places it after The Phoenix Saga - Part V Child Of Light (1994) when Phoenix (Jean Grey) hides the M'kraan Crystal in the sun. Cerebro detecting Jean toward the end places it before Savage Land, Strange Heart - Part One (1994) when Wolverine (Logan) indicates Jean being examined on Muir Island.
Longshot (1996), Obsession (1994), and Cold Comfort (1995) also take place during this same time period. Due to the absence of Cyclops (Scott Summers) in Longshot, that episode may take place concurrently with the events of this one. Disney + listed this episode as season 3: episode 8.
First appearance of Zebediah Killgrave. While not referred to as such in dialog, Kilgrave is known in the comics as the Purple Man.
