Sven (Sven and the Scarf)

From Tardis Wiki, the free Doctor Who reference

Sven was an alien researcher at GeoComTex in 2012.

He once located the Fourth Doctor's scarf and began examining "alien artefacts" left behind on it; though some of the artefacts turned out to be less than riveting (they included a jelly baby and what looked for all the word like a piece of green bubblewrap), he documented them all faithfully and filed them away in duly-labeled glass containers. On the same day, the Metaltron arrived at the Vault. (WC: Sven and the Scarf)
