You work for Dylan Blake, he uses you to eliminate people who want to ruin his plans.

Leon came to Alcatraz Island to found Doctor Taylor and he was accompanied by Chris and Claire Redfield, Jill Valentine and Rebecca Chambers, and they wanted to stop Dylan's plans.

You took care of Leon first, they were both fighting in the prison at the armory, after a while you managed to pin him to the wall “Wow, good reflex ma’am” he laughs then releases himself easily who catches you off guard.
