In Meg 2: The Trench , Meiying’s mom Suyin (the “mom” from the first movie) is already dead before the story starts, and the film only briefly explains this in dialogue and a slideshow, without giving a cause of death.

What Happened to the Mom in Meg 2?

On-screen explanation

  • The “mom” you’re asking about is Suyin Zhang, Meiying’s mother from The Meg (played by Li Bingbing).
  • In Meg 2: The Trench , we learn she died sometime after the events of the first movie , off-screen and between films.
  • This is revealed during the Oceanic Institute’s 10th‑anniversary celebration, when Jiuming gives a speech and a slide shows that Suyin died in 2021, about three years after the original megalodon incident.
  • The movie never reveals how or why she died; there’s no flashback, no detailed story, and no emotional subplot built around the circumstances of her death.

So, in terms of plot:

By the time Meg 2 begins, Meiying’s mom is already gone, and the film just confirms she died a few years earlier, without an explanation of the cause.

Off-screen / behind-the-scenes angle

Fans have speculated that Suyin’s off‑screen death is mostly a writing and casting choice rather than a big story mystery.

Common points you’ll see in forum and article discussions:

  • Li Bingbing simply didn’t return for the sequel, with commentary suggesting scheduling, career focus, or production reasons, though nothing has been made officially detailed to the public.
  • To explain her absence cleanly and prevent dangling questions about where she is during all the chaos, the sequel chooses to state that Suyin passed away before the events of Meg 2.
  • Because the cause is never explained, viewers often fill the gap with theories (illness, accident, something unrelated to the Megs), but none of those theories are confirmed in the movie or official canon so far.

Quick FAQ style recap

  1. Is Meiying’s mom in Meg 2 at all?
    • No, she does not appear; she’s already deceased by the time the movie starts.
  1. Does the movie say how she died?
    • No, it only reveals that she died in 2021; the cause is never stated.
  1. Why did they kill her off-screen?
    • Officially, the film just presents it as backstory; outside the story, it’s widely thought to be because Li Bingbing did not return for the sequel, so the writers closed her arc off-screen.
  1. Is this considered final for future sequels?
    • Yes—within the movie’s canon, Suyin is dead, so a straightforward return in future films is essentially ruled out unless they retcon or use non‑literal appearances (memories, recordings, etc.).
