For a floating purple monitor, she is pretty adorable! Which I never thought I would say after dealing with 343 Guilty Spark in Halo 1, 2, and 3. Anyone else like her and/or think she should come back for Halo 6?
Hell yeah, Exuberant Witness is amazing! Can't believe that 343 managed to introduce such a insanely awesome character so late into the campaign. I certainly hope she returns in Halo 6. Since she is a the monitor of a Bulder installation she could probably supply Chief and co. with some neat new toys :D
Witness was a good character, it was interesting to see an almost "typically girly" character displayed in that way. I thought it worked well. Especially with the AI thing with Cortana. And the UNSC becoming friends with one of the potentially most important forerunner AIs. I really hope the exuberant plot line continues.
For a character that came pretty late into the game and had so little time for it to show anything remotely about it's self, Exuberant Witness is a very well and amazing character and i'm pretty sure it is now on my top characters list.
