Answer: High Valyrian
Commonly used by Melisandre, High Valyrian is one of the many languages we can see on the show. When she meets Thoros of Myr in the Riverlands, another priest of the Lord of Light, we can see that he also speaks the tongue.
Daenerys is also able to speak it fluently, and we assume that other Targaryens were also fluent in High Valyrian, since the original seat of this House was the now ruined city of Valyria, in Essos.

Answer: A newborn slave child
Daenerys travels to Astapor to buy an army. She has heard of the Unsullied, who are elite warriors known to show no fear and unquestioning obedience. She meets with one of the slave masters, Kraznys mo Nakloz, who shows a squadron of Unsullied to her. Daenerys learns Unsullied are trained from the age of five to fight and feel no emotion. The slave master has one of the Unsullied sliced across the chest to show that the warrior does not even flinch at the pain. To prove the Unsullied kill without question or mercy, they have to kill a newborn slave child to complete their training. Upon learning this, Daenerys has to appear pleased to keep up appearances, but we know she is making a plan to destroy the cruel slave masters and make the Unsullied free men.
