Yes, indeed.

Good luck!

Saruman, talking trash about Radagast.

Absolutely! Your go, Tuor!

Okay. How about this partial quote?
(The whole quote would give it away).

Erendis to Aldarion

Yep. Too bad they were 5 or 6 Ages to early to see
a marriage counselor to save that relationship.

Well, I'm not sure if that would have helped them ;)

Tuor to Voronwe?

Exactly! :)

good luck!

Turin to Niniel

Yep! Your turn, Guinevere :)

Thanks!

A hint perhaps?

gandalf to pippin?

No, not Gandalf to Pippin.
I had left out the two last words; the full quote is:

"I do not think that either of those things are true, my son."

Just a guess...Morwen to Túrin?

Well guessed, Carnimírië! :)
But what are the things she is referring to ?

"Then I think that he is dead, for no one could keep him from coming back to help us, if he were alive." quoth Túrin. Morwen thinks neither of those things are true.

That part is quite sad :(

Exactly! Please proceed!

"But if you are glad to see me living, then you are the last in Middle-earth."

Túrin to Mablung, when they met after Túrin had killed Glaurung and Brandir

You've got it!

Thanks!

Tuor to Voronwë at the crossing of the road, on the way to Gondolin.

Correct !
 

That was a fast answer, Carnimirië ! :)

Well I'm re-reading UT now...just finished the Narn in fact.

Andróg said this to Túrin about Mim

Exactly. Your turn :)

thank you!

Voronwë to Tuor, speaking of his voyage to seek Valinor.

That's it ! :)

"The vengeance of Sauron lives on"

Isildur to Elendur
(the quite interesting UT Isildur, not the rather dense PJ Isildur)

Correct.

Next:

Thingol to Nellas, in the trial of Turin.

Correct. Your turn.

Next one:
