Wow, the attention to small details in this show is really impressive.
Been watching Nearly On Red's youtube anyalis of the show and there are so many hints and little details given in the early episodes that come up again in latter epsiodes.
For example, episode 3 has 02 mention that the plantation's squad has been wiped out before. This apparently doesn't register with the kids till episode 8 when Miku discovers the picture of said squad.
Another cool little detail. The song (Vanquish) that plays in the first episode when 02 pulls Hiro into the cockpit and kisses him:

The lyrics are actually in English. Good thing one could understand it because its quite spoilery for the very first episode. lol
I really do have to rewatch this whole series again once it ends. I want to see how many of these small details I either missed or failed to recognize their significance.
