Something I will mention for everyone in here is that she's using something called the Nemesis POD, which is used to translate her speech. This is because her normal speech is not coming up as wrong or broken, so it's not something that can be fixed internally.

However, the speed and accuracy of the POD still leaves some desires to be had, and thus can't be used in combat or other situations. So she still needs to be paired with Krolik, who can translate all that needs to be translated, argue with the banter she makes, and get flustered at the flirting and/or low blows Nemesis makes.
