In early 2008 He was wounded by John Druitt when Druitt had sought out Ashley Magnus during his and Ashley's meeting at an warehouse on the Eastside of Old City. Sylvio eventually recovered enough to make his way through the warehouse to help Ashley, taking out Druitt by tasering him. Henry was then called for transport; bringing the van to pick up Ashley and Druitt. Sylvio tagged along with them on their ride home, being dropped off at Dr. Lim's along the way back to the Old City Sanctuary.

Several days later, he provided incomplete information to Dr. Helen Magnus and Ashley, failing to notify them of the Keepers of the Dead (or just the sheer amount of them) protecting the crypt on the island in Scotland.

A short time later, he accompanied Magnus and Dr. Will Zimmerman to the Himalayas to capture a yeti. However, the creature they captured was actually a migoi posing as a yeti. During transport, the migoi caused the plane to crash in the Hindu Kush. Shortly after the crash, the migoi killed Sylvio, tricking him into believing he was seeing his significant other Giselle. Upon discovery of his body the next morning, Magnus noted that the Sanctuary Network had lost a valuable member of their team.
