Just as they were wondering what Loki was going to do next, they felt a vibration in space. The vibration was akin to the spatial fluctuations that occur when the barriers of the extradimensions are broken, so the vibrations were familiar. But they couldn't tell what the source of the vibration was.
The vibration was subtle and very weak. It was something they wouldn't have noticed if they hadn't had the entire space in the area on lockdown.
But even after noticing the vibration, they couldn't tell what was creating it or where it was coming from. The best they could tell was that it most likely had something to do with Loki.
They all scanned their environment in order to spot whatever Loki might be up to. But just as they were looking around frantically, the world around them froze.
For what lasted for an eternity, but felt like an instant for them, the world was frozen. Then the world faded away.
