I wouldn't want to be Daniel explaining to Sha're how he could have kept her baby COMPLETELY SAFE but instead he let the kid live like a refugee. That would be the end of that marriage if a step-dad treated my kid that way.
Oh, that's easy. Share is a simple, trusting girl from a primitive culture. All Daniel has to do is explain that he had a Tom Petty song stuck in his head like an ear-worm --
It don't really matter to me baby,
You believe what you want to believe,
You don't have to live like a refugee.
And then she'll recall the horrors of being possessed by Apophis' queen, and realize that what Daniel must've suffered with his "ear worm" singing that dreadful song to him over and over and over must've been far worse than being possessed by a high-ranking Goa'uld, and all will be forgiven.
