They're not actually related. The "healthier" gentleman is just a very kind person who decided to keep the other guy company in his last moments.

He says "Farewell, my boy" in the same manner Lydia greets Corvo with "Hello love" at one point in the Hound Pits.

Or as a real-life example - (usually) older women working in retail or hospitality might call customers "Dear" or "Darling" or something similar, in an over-familiar (ibut no less genuine) greeting or farewell.
