a virus or a pest?

[bower]

All my plants are looking great so far except for this one... if this is a virus spread by little pests I'd like to know it so I can remove the infected plant.
This plant is a Lycopersicoides cross LA 4268, which has a gene for botrytis resistance. The plant and its three siblings have looked kind of miserable from the get go, but I figured this was just their nature, and maybe not liking the cold. Yellow spots on some leaves looked like cold stress or nutrient stress symptoms, but this is different.
Is this what a mosaic virus looks like?
