Peter Grasso

When a man enters an office in Boston for a meeting, he becomes disoriented and collapses, only to have his veins erupt and spray blood everywhere. Shortly after Olivia and Peter arrive at the scene to investigate the bizarre case, it’s discovered that a lethal virus – with deep ties to something very valuable – is spreading, so the CDC moves in to quarantine the building and eradicate the pathogens. Isolated inside with the rest of the exposed office employees, Peter and Olivia face life-threatening circumstances, sending Walter, Broyles and Astrid on a frantic search for a solution to save them.

Oliver collapses at a charity event and reveals he only has 24 hours to live. Clark and Chloe call Davis for help but his prognosis is grim. Delirious, Oliver flashes back to when he was stranded on an island and first learned how to use a bow and arrow. He also recalls meeting Tess for the first time on that island after she had been kidnapped by a drug runner. Meanwhile, Chloe decides to use her new powers to help save Oliver, shocking Clark.
