Reseda refers to her actions way back in the Cats Are People Too storyline.

Fake Integra: Who are you to question my identity?

Reseda: Just your average, ordinary chordewa…

Fake Integra: So you’re a self-proclaimed enemy of Hellsing?

Reseda: Hey! It wasn’t personal! I just wanted to see if I could do it!
