How does Ruby know for sure Masked Person X didn't use her Semblance? How does Ruby even know that stranger's Semblance? Either it really is the crew's way of telling viewers or Ruby assumed it wasn't Semblance because the glass came from a bottle and was then launched instead of simply materialising. Or maybe some other reason. And that "bottle" was a Dust cannister, just like the ones we saw in V1E1 when the henchmen were loading up on powdered Dust to steal in From Dust Til Dawn. The concept art for Cinder's stealth suit even includes a pouch for Dust (the notes specifically say it's for Dust), though the final version of her stealth outfit is pretty different from the concept art, but I think she kept that pouch.

Whenever Cinder made obsidian, the Dust designs in her clothes lit up, which points to the obsidian coming from her using Dust. Even the glass during the Amber fight came about through the Dust designs on Cinder's sleeve glowing and the dirt she kicked up heating and melting.
