Are you wondering why such titles like, "MadMax," "The Boy Who Came Back to Life," and "The Pumpkin Patch" appear on the official "Stranger Things" Season 2 trailer? Some fans speculated that it could be the major spoilers of Season 2. Here's why!

If you haven't seen the trailer for "Stranger Things" Season 2, it is actually simple, they used the introduction or opening credits of the series. However, instead of showing or introducing the logo "Stranger Things" only, it shows titles for the nine-episode, and these are, "MadMax," "The Boy Who Came Back to Life," "The Pumpkin Patch," "The Palace," "The Storm," "The Pollywog," "The Secret Cabin," "The Brain," and"The Lost Brother." Then the trailer ended with the phrase "Season Two."

Episode 1 is titled "MadMax." There is a new character named Max and she will be introduced in Season 2. She is tough, confident 12 to 14 year-old girl, who acts like one of the boys, described by TV Line. She also rides a skateboard, and could be a little mad.

Episode 2 is "The Boy Who Came Back To Life." Some reports suggest that this could be about Will (Noah Schnapp). If you will watch the last episode of "Stranger Things" Season 1, the episode title is the same as the headline from an article shown in Season 1.

Episode 3, "The Pumpkin Patch" could be the eggs from the upside down world, Huffington Post theorized.

Episode 4, "The Palace." Online rumors suggest that this could refer to the Hawkins Lab, however, in a previous report, Duffer brothers said that Season 2 is surely a continuation, and the episodes will venture a little bit outside the Hawkins.

If this is not about the Hawkins lab, some online rumor suggests that this episode is referring to Nancy (Natalia Dyer).

Episode 6, "The Pollywog" could be about the slug-thing Will coughed up. Pollywog is another term for tadpole. In the last episode,
Will puked out something. So maybe this is about Will.

Episode 8, "The Brain" and Episode 9, "The Lost Brother" could be about Eleven, according to the Huffington.
