"And he was telling them, 'I sent them away. Those girls, I sent them away. They can help themselves. I don't want to be in trouble,'" Immaculee explains.
"The first time the killers came here to search your house, did you think they were going to find the women and kill everyone, including yourself?" Simon asks Rev. Nzabahimana.
"Yes. Yes. I thought so. I thought that if they had seen them they would have forced me to kill them or they would have killed me and killed them as well," he replies.
"You think they might've forced you to kill them?" Simon asks.
"That's what they did elsewhere," Nzabahimana explains. "Wherever they found somebody hiding people they forced them to kill them. And afterwards they also killed the person."
During the first search, one killer actually put his hand on the door leading to the bathroom, but he never opened it. After that the pastor showed Simon how he moved a bureau in front of the door to hide it from future searchers.
Everything outside the bathroom where Immaculee and the others were huddled, the entire country, had become a killing field. Hutus armed with machetes searched every house, every hill and killed every Tutsi they could find.
What prompted the genocide? There are things you can point to. The Hutus had long-standing resentments against the Tutsis, who formed the nation's elite. They had the better houses, better jobs.
Radio broadcasts called day and night for the Hutus to go out and kill Tutsis and the Hutus were told by their own leaders that if they didn't join the killers, they would join the dead.
There are things you can point to, but do they explain what happened? What could possible explain what happened?
Here's one explanation from one killer who had been Immaculee's neighbor, Alex Ntibirukee, who spent 11 years in prison after admitting he killed six people: "They told me that I would be rewarded with a piece of land and a banana plantation. They told the same to other people, but you see they didn't give me any banana plantation."
"They told you you would be rewarded with a banana plantation, if you did what?" Simon asks Ntibirukee.
"They told us to kill, and we killed. We just did it," he says.
Asked what exactly he did, Ntibirukee says, "I got my machete and a nail-studded club and started killing." He killed his neighbors, and told Simon he had nothing against any of them; two of the victims were Immaculee's second cousins.
Asked how he killed them, Ntibirukee says, "I chopped one with a machete, and killed the other one with the nail-studded club."
He had grown up with Immaculee and been her family's handyman. Asked if he and the others would have killed Immaculee had they discovered her, Ntibirukee says, "Because of the way I was, I would have attacked her definitely."
For days, then weeks, then months, the seven women stayed squeezed into the tiny bathroom, surrounded by evil.
Asked what was going through her mind, sitting in the bathroom hour after hour, Immaculee says, "How are they going to catch us. Where they will start cutting you. If they will rape you."
She says she was terrified the entire time she was cooped up in the tiny space. They all expected to be killed, eventually. One said she just hoped she'd be shot and not tortured; another made the pastor promise to put dirt on her corpse so dogs wouldn't eat her.
And what did the women have to eat? Not much.
"I remember sometimes we used to eat just like, beans. And there was this little insect that came out of the beans. And he brought it. It was 'Jesus, well how am I going to eat it.'"
But after a while, she managed to eat, by closing her eyes. Still, Immaculee said she lost 40 pounds - one third of herself disappeared during her three months hidden in the bathroom.
"I was completely a skeleton. I remember me myself thinking, looking at my hands. And I was like, 'This is what the biologists used to tell us, you know. We are really-we have a skeleton like this.' It was completely like-I can see every bone," she remembers.
Looking at herself was like a personal anatomy lesson. "It was shocking," she tells Simon.
Also shocking was that to keep their presence secret from others in the house, they couldn't flush their toilet unless someone else in the house flushed the toilet on the other side of their wall. And they couldn't bathe.
"We didn't have any next clothes or any toothbrush to brush our teeth. Nothing. We couldn't," she explains.
