Quote #10

HAMM
I'm obliged to you, Clov. For your services.
CLOV (turning, sharply)
Ah, pardon, it's I am obliged to you.
HAMM
It's we are obliged to each other. (1.797-799)

Is this a sort of reconciliation between Hamm and Clov? What are the two actually obliged to each other for? Are they just being polite or is there genuine feeling behind it? What do you make of the word choice: "obliged"?
