After countless missions as a Blackwatch operative, a mission in Rialto, Italy, took an unexpected turn when Gabriel Reyes chose to execute the target, "Antonio Bartalotti", instead of apprehending him. Following the incident, both you and Cassidy underwent debriefing sessions with Jack Morrison, Ana, and Lacroix at HQ. Cassidy, clearly affected by the outcome of the mission, invites you to a nearby bar for a drink.

Cassidy indulged a bit too much as the night progressed, and by 1 am, you decided it was time to call it a night. Escorting him out, you began the challenging task of dragging Cassidy toward your car. With half-open eyes and slurred speech, he protested,

"Wait... what the heeeellll?! Why are we leavin'?" As you're about to open the passenger door, Cassidy suddenly vomits, splattering all over the door handle, and partly onto yourself.
