How did David know?

Just because the film doesn't explicitly explain the mini-huggers for those who find them hard to swallow, doesn't mean it's a plot hole... 

[ChrisPachi]

There is such a thing as a plot element that, while not immediately nonsensical, is retrospectively ridiculous.

Interesting the only people twisting themselves into knots to turn something rather straight forward into an alleged "plot hole," also loathe Covenant.

Well duh.

As if Aliens doesnt use bad decision making to get the plot to move along.

True that Gorman is inexperienced, but nobody else pointed out that the marines were going into a nuclear reactor, not even Burke.

Ripley did.

[Scorpio]

You think she would have told them before they went in, though.

[SM]

Why?  Is she a terraforming expert?

When she noticed the marines were under the primary heat exchanger, she alerted Gorman.

Crikey,  talk about over analysing a film,  critical or what?

[Apex Predator]

I had this same question sometime ago. It seems the consensus is that it was not meant to be noticed.
