if something is water, that means the molecules of the water is touching the molecules of the object. Water molecules touch each other so water is wet.
if you wish to include the fact the atoms never touch each other, then let me say if they never touch then nothing can be wet.

Yosemite means "They are killers" so maybe Synth kills/contains dangerous beings made out of mysterious substances, knows a ton of things about technology, and accompanies others and helps them.
