at four days to zero hour, the alien plant has grown to cover many areas of the base. after sg-1 go missing on their off-world mission, a goa'uld named ba'al contacts stargate command and suggests an exchange of the captured sg-1 against camulus, another goa'uld who requested asylum on earth several episodes before. with the help of camulus, a potent power source is found and brought back to stargate command, only to find it tainted by camulus (powering it up could result in the destruction of the solar system). with the sgc suffering from a temporary electricity failure caused by the alien plants, ba'al's renewed contacting only results in o'neill's mocking. exhausted by sleep deprivation two days to zero hour, o'neill finishes his letter to general hammond to inform him of his resignation.
