Did Zero-Two regain her memories far earlier? [spoiler alert] I'm doing currently a quick rewatch in order to find out hidden details, symbolism etc..

I noticed a possibility that Zero-Two could regain her memories far earlier than Hiiro. Even before visiting "Garden".

It would be even possible that she regained the memories, but didn't recognize him as him just after first meeting, or could have doubts if he is really he for long time or still could be afraid of rejection for being a demon.

Following this way of thinking, she could even believe that her "old darling" died in a battle long time ago like other yearlings and the person she met recently is only a clone. (Just as former 13th squad or Nana)

Obviously she seems like she does not recognize him during their first meeting (in recent timeline) but it seems like it might happen after about 1st-2nd episode.

Could you please help me find some references to similar investigation?

Or maybe I will try to state my question directly: Did she regain her memories before Hiiro? If yes, when approximately?
when zero two first met hiro she didn't recognize him, and was using him as a fodder to help her find her "real darling", but she didn't know that hiro was her real darling. then later on during a battle, zero two realized that hiro is her darling. but she doesn't remember the memory when they were little, she just remembered that hiro is her darling
