User blog comment:Battlefield4us/Things that were not in Volume 2/@comment-3257939-20141207165833

For what I've seen in interviews and commentary, it seems that they were planning to add all of this stuff but ran out of time.

For example: Do you remember the Production Diary where Velvet's combat gear was revealed? In that diary, you could see them working on a scene where Velvet is talking to someone in the cafeteria. I have this feeling that Team CFVY was meant to be introduced in the very first episode but for some reason they decided to save them for later.

Also, Neo's voice. According to the Afterbuzz, Neo is not mute since she has a voice actress but that's still in process so since they couldn't get the voice actress on time, they had to leave Neo without any voice for an entire volume making people think she's mute which then again, it's possible since that business with the voice actress can always go wrong and end up in nothing.
