"What do you mean Dana is also angry at you?"
The two of them are at the WIZ lounge sitting beside each other, shoulder to shoulder. They are basically whispering to themselves since they don't want any members of the team to hear what they are talking about.
"You are her boyfriend. You know Dana does not really get angered very often, however, this time, she is resentful towards me. And it was all because of you." she hissed at him.
She was trying to keep a neutral expression on her face, in order not to attract any attention from the other team members. But right now, she is having a difficult time keeping her emotions in check.
She is not actually blaming Grand, although she agreed reluctantly when he asked her for a favor of not bringing up his ex-girlfriend to Dana's attention. The fact that she agreed to it did not change.
Hence, as much as she is pissed off with Grand, she is angrier with herself.
