Cortana's Data Chip

So in the trailer John-117 pulls out, what I would assume is Cortana’s Data Chip. Then I remembered, wasn’t the Data Chip disintegrated at the end of Midnight?

Also, What do you think Chief is going to do with the Data Chip?

  1. Already a thread on this.

  2. he didn’t put the data chip in the network module, but just basically ‘scanned’ it so Cortana could pass through over to it.
