Captain Samantha Carter bonded with her and was more than a little reluctant to leave her at the bottom of an abandoned nuclear facility, where the bomb would go off, only killing Cassandra. However, it occurred to Carter that Cassandra's condition had deteriorated when she was brought near the Stargate and she had returned to her normal condition when taken far enough away from it. Therefore, she correctly concluded, the bomb inside Cassandra would only go off if she was in close proximity to the Stargate.
