"The Illustrated Stacey" was the twenty fifth episode of Stargate Infinity.
After Stacey allows aliens to paint a beautiful design on her skin, she learns the horrifying truth: they haven't used paint, but rather, an alien microbe that's spreading over her entire body, causing it to change.
The team arrives on a planet and helps the native Ner'alds against an energized dragon-creature – a late arriving Harrison manages to knock it out. Stacey and Seattle admire the locals' markings and the guys end up teasing Stacey into getting a marking. It turns out that the paint is made of microbes and they start spreading on Stacey. They're not toxic, but will cover her entire body. They need a stream with mud to make a removal salve but another energy-resistant creature attacks – Gus takes Stacey while the others hold off the monster. Avoiding a variety of dangers, Gus and Stacey make it just in time but the stream has dried up. A persistent bug creature that has been following them finally latches on to Stacey and sucks off the microbe.
Gus: I'm not losing my niece to a tattoo.
Harrison: Why can't aliens ever cook cheeseburgers?
