I did think that was rather cool (although GL commercials and previews ruined the surprise by showing Aya's new Mobile Form early), however the whole time I couldn't help think that a lot of inspiration was taken from Mass Effect's EDI and what was, subsequently, done with her character.
Both are A.I.s, both become more emotionally sentient, both form strong emotional attachments to a particular character, and both, eventually, get attractive Cylon Bodies. *For the Record,* I'm not saying it's a bad thing to make these comparisons.
I love Aya in GL, I think she's a fantastic character, and I loved the Mass Effect series (horrible endings and all...) however the parallels are rather striking. Still, really great job all around. The series continues to be a hell of a good show and I hope the same crew is working on the forthcoming CG Batman.
