I have been browsing the forums for months now. ^^ I don't recall seeing such a thread. But if this is a repeat, I'm sorry.
I have found myself pondering about Ursa every single time I think of Avatar. I have come up with some wild things about her. But I keep coming back to a simple question that will probably have a huge effect if she's alive and doesn't know.
Does she know that her son was scarred and banished like she was?
At one point, I cannot see it. I personally think she is dead. But if she is alive, I would think that if she knew her child was banished, she would do all she could to find him and be with him again.
At another, I can. If she's alive, she may have been too scared to go find her son and comfort him. Though she may have send messages from Iroh to keep tabs on her son.
So what do you think? Does she know, or doesn't she?
