Killed by Quinn
Sebestian Balfour was the finance of Veronica Donovan.
Originally engaged to Veronica Donovan, he cancelled the wedding because Veronica was putting too much effort in Lincoln Burrows's case. (1x3) Veronica says that she's unsure at first and maybe they should postpone it for now. Sebastian counters with an ultimatum; if Veronica wants to postpone, then they should cancel it.
