In context, Emma says she did so because she wanted to talk to him about what happened. Quote: "I haven't faced him since he assaulted me and I want to talk to him about what happened. I try to say this in a friendly tone, so that he doesn't get scared. I don't want him to avoid that conversation. I'm being irrational, thinking that talking with him would help me."

It is relatively common for rape victims to avoid conflict and try to act as if nothing happened. She agreed to bring her friends over, again, because she wanted to talk to him about what happened. She claims she was cordial because she did not want him to avoid the conversation.

According to the RAINN, this is not uncommon.

Rape Trauma Syndrome

There are three phases to Rape Trauma Syndrome:

1. Acute Phase: This phase occurs immediately after the assault, and usually lasts a few days to several weeks. In this phase, individuals can have many reactions, but they typically call into three categories of reactions:

Expressed — This is when the survivor is openly emotional. He or she may appear agitated or hysterical; he or she may suffer from crying spells or anxiety attacks. Controlled — This is when the survivor appears to be without emotion, and acts as if "nothing happened" and "everything is fine." This appearance of calm may be shock. Shocked Disbelief — This is when the survivor reacts with a strong sense of disorientation. He or she may have difficulty concentrating, making decisions, or doing everyday tasks. He or she may also have poor recall of the assault. 2. The Outward Adjustment Phase: During this phase, the individual resumes what appears to be his or her "normal" life, but inside is suffering from considerable turmoil. In this phase, there are five primary coping techniques:

Minimization — Pretends that "everything is fine" or that "it could have been worse." Dramatization — Cannot stop talking about the assault, and it is what dominates one's life and identity. Suppression — Refuses to discuss, acts as if it did not happen. Explanation — Analyzes what happened: what the victim did, what the rapist was thinking/feeling. Flight — Tries to escape the pain (moving, changing jobs, changing appearance, changing relationships, etc.).
