Summary: Teal'c thinks about his changing role
From the moment of his birth it was known who Teal'c was. He entered the world and was given his roles in life. He was the son of a respected Jaffa, the promise of a great warrior, little brother of Tura'c - and a slave. With the death of both parents he ceased to be a son. When his brother died aged sixteen during his first battle he ceased to be a brother. He was still a great warrior - and still a slave. When the Goa'uld finally fell, Teal'c continued to be a warrior, using strength of will and the power of words to fight for his people. He was no longer a slave of any Goa'uld.
When Daniel Jackson falls, when there is no enemy to fight and only fear and pain to keep Teal'c company as he waits for familiar eyes to open once again, Teal'c accepts that he is still a slave. Some bonds are unbreakable and willingly worn. He does not know who or what Daniel sees when he looks at Teal'c. Whatever, whoever, it is makes his friend smile in welcome, makes him glad to see him.
Teal'c is no longer so certain of who and what he is but he thinks Daniel Jackson knows and that is enough.
