Well it wasn't the line actually..... She took off the tip of the faucet, the nozzle, and dunked it in CLR. It wasn't screwed on tight enough and was spraying a bit, something I realized, I just didn't make a connection that it could somehow be the source of the leak in the cabinet under the sink.

Tightened the nozzle with the wrench, problem solved...

How in the world did it cause water to go underneath though? Looks pretty sealed.
