Title of Series Finale: "Felina" : Fe Li Na (Blood, Meth, Tears)

Redditor explains:

Fe Li Na is a play on "Finale." Fe (Iron) Li (Lithium) and Na (Sodium) are all in fireworks. Fe, depending on how hot it burns, will produce different colors. Li makes red fireworks, and Na produces gold/yellow fireworks. Granted, fireworks can contain many more things, but I think they're trying to say that the finale will be a grand display, like fireworks.
