re: **Once Upon A Time**, Season 2, Episode 18 "Selfless, Brave and True"

non disney allusions include:

as a nod to the ties between the production teams of Once Upon a Time and Lost, the new show contains allusions to Lost, and is expected to be a continuing theme throughout the series.[19][33] For example, many items found in the Lost universe, such as Apollo candy bars, Oceanic Airlines, and MacCutcheon Whisky, can be seen in Once Upon a Time.[34] The town clock was stuck at 8:15, an allusion to Flight 815 from the Lost universe. An Ultimate Wolverine vs. Hulk #3 comic read by the character Henry in episode 9 of season 1 was written by Lost executive producer Damon Lindelof. In addition, former cast members of Lost have made recurring appearances on the series, with Emilie de Ravin being the first post-Lost regular to become a full-time regular on Once Upon a Time.

In "What Happened to Frederick" where Henry is given Space Paranoids, a reference to the film Tron, whose logo can also be seen in Henry's lunchbox in "The Stranger".

In Rumplestiltskin's castle was the scythe featured near the end of the final season of Buffy the Vampire Slayer, albeit colored differently. In episode 8 the true name of "The Dark One" is Zoso which is also one of the symbols in the album Led Zeppelin IV.[34]

In the episode "Lady of the Lake," two significant allusions are seen. The first is to the Narnian series in which the "wardrobe" is the only portal. The other allusion is to the story of David and Goliath; Snow kills the ogre, "Goliath," in the eye.
