the dead guy in the morgue had them, Esher has them, and after re-watching last weeks episode, Isaw that Curtis Chenalso had them..
A few episodes back, Esher told Kira that they were a mark of the freelancer time travelers, but I guessthat would make Curtis a freelancer posing as a liber8 member??
I don't remember seeing the marks on any of the other liber8?smembershands, andKellog clearly did not know about the freelancers, as I remember him puzzling about ita few episodes ago when his new business venture was taken from under his nose by Esher.
At any rate this could mean thatthereare more freelancer"sleeper agents" not onlyin the liberate terrorist group, but also incharacters previously thought to be from this time...
