Alucard and Integra explain the situation to Seras — hastily.

Alucard: Which is why, as soon as we got up, we were going to find Walter and look up all known data on fangirls, so that we can work out how to remove them.
Seras: So let me see if I understand this…

Seras: These little girls on your shoulders are from another dimension, and attached to you? And more are apt to fly into this room at any time…through some kind of portal?

Seras: Making what sort of noise?
Integra: A high-pitched “eee.”
[EEEEEEEEEEEE!!!]
Integra: Yes, like that.
Seras: That wasn’t me…

Fangirl: Seras is sweet and Seras is cute and Seras is nifty and Seras has a big big big gun and Seras overcomes all her obstacles and she’s a servant to Alucard and she is the most utterly spiffish!
