Behind the scenesEdit

"I should have you beaten. I should lock you in that cell and cut you down to synthcubes and water. I should… should…"

Synthcubes were first mentioned by Marshall Kay Cavarat in the video game Star Wars: The Old Republic; she will only mention them if a male Smuggler character flirts with her.
