Serena Vonda is a character mentioned in Mackenzie King's blog. She is described as a second year recruit at Athena Astronautics, and told King that UFO fanatics were reading her blog. It is possible Samantha Manus was one of these fanatics.
Athena Astronautics was part of a viral marketing campaign of several websites in the Metroid universe, to promote the upcoming release of Metroid Prime 2: Echoes. In the actual game, one of the deceased Federation Marines from GFMC Task Force Herakles Squad Bravo is named LCPL R. Vonda. This could imply a relation between the two.
