Go to the War Room in the new part of Haven (New Haven City).

There are many computer screens around, but translated these have a deep meaning. Aparently a Naughty Dog game designer lost his/her dog a year before the game was made. These lines translated say:

There will be no other

Morgan.

I will always love you.

Good Dog.

Morgan I love you.

Thriteen Years hard time.

And on one computer:

Morgan is so ill.

Missed even after

a year has passed.
