Events of Red Dead Redemption 2
Hosea Matthews introduces Seamus to Arthur as a new prospective business partner. Seamus states that he does not like working with amateurs. Hosea suggests a chance to prove to Seamus that the pair are skilled, and not amateurs. He tells Hosea that he will only do business with the gang if they carry out a job for him; stealing a stagecoach purchased by his cousin-in-law.
He also makes an appearance in a stagecoach robbery, which was a tip provided by Alden Carruthers. After stealing a stagecoach, the player must take it to Seamus for payment.
- He may own an Australian Shepherd, as one can often be seen near his fence business.
- As of Patch 1.14, his Fence is missing its table but the candle is still there.
