I didn’t even know I had

She took a sip of wine. ‘Yes, Jade. He did answer a lot of questions. Some that I didn’t even know I had, like What does hypermobility mean?’

Some that I didn’t even know I had ??

Dear T'bell:

Some [questions] that I didn’t even know I had ??

In other words, he gave me a lot of information. He answered all my questions, and he talked about many other things as well.
This could be sincere, as in, 'He is so knowledgeable! After he left, I realized he had talked about things I wasn't aware of before.'
or, it could be sarcastic, as in, 'He thinks he knows it all! He never stopped talking the whole evening!'

I hope this is helpful,

Petra
