She could have closed the gap and gotten her hands on Amy at any moment, but she didn’t. She was a cat with its prey, and Amy didn’t have anything that could help her get away.
Right. After Crawler’s adorable side, it’s surprisingly easy to forget that Siberian is also catlike.
Well, tigerlike, but there’s not much difference, and it might be partially an act to make the monochrome stripes make thematic sense.
Amy ran and created some distance, getting just far enough that she might think she’d escaped, then Siberian would appear in front of her, or to one side. It happened once, twice, then three times. Each time, Siberian drew closer.
Siberian also has another trick on her side: She can, for many intents and purposes, teleport. Though she might only be able to go back to where their real body is.
I’m not sure if I actually mentioned this yet (I don’t think I did), but not too long after it was revealed that the monochrome decoy was her power, it occurred to me that this would be how she got past the blockades unseen in the Case 01 video: She’d dismiss the decoy and resummon it, like Grue did at one point.
Though in retrospect on the retrospect, it is possible that their power is constantly on, and Grue just severed his connection to the power and then reconnected.
