One person asked this:

Guest: If the Warblers knew about Kurt's allergy, then why would Blaine be confused about what anaphylaxis is? I imagine he would have mentioned that when telling the warblers. Or Wes would have explained it. This doesn't really make sense.

1. I don't really understand your question.

2. Wes wasn't even in this story?

3. I honestly didn't even know a deathly allergic reaction was called an anaphylaxis until I researched about it online. Blaine knew his boyfriend was deathly allergic, but didn't know what the actual name of it was.

The Warblers didn't know about how Kurt could die if he ate nuts. They just knew that he was allergic so made sure not to give him any?
