Events of Red Dead Redemption 2
Tavish is first seen at Caliga Hall talking to John Marston, Javier Escuella and Arthur Morgan about Catherine Braithwaite's prize horses, and promises them that they can get five-thousand dollars for them. The trio happily accept the offer and steal the horses from the Braithwaite Manor, although Tavish's promise turns out to be false when they get a mere seven hundred dollars for them, instead of the promised five thousand.
Shortly afterwards, after Arthur and Sean MacGuire burn down the Gray family's tobacco fields, Tavish and Leigh plot revenge on the Van der Linde gang. The Gray family offer gang members a security 'job' in Rhodes, which Bill Williamson and Micah Bell accept. Those two, along with Arthur and Sean, are then ambushed in the centre of Rhodes, resulting in a large gunfight. While the Grays manage to kill Sean, all except for Tavish are wiped out, including Leigh.
Sometime after the battle, Tavish commits suicide. His body can be found on the back porch of the main building at Caliga Hall as a point of interest, next to a letter from Edinburgh University historian Malcolm Moffat, which reveals that Tavish's ancestor Ross Gray was not an exiled Jacobite as previously believed, but a spy for the Duke of Cumberland who was forced to flee from Scotland.
