Gundam 00 episode 8 seiyuu frustration

Tieria Erde has a female voice during episode 8 of Gundam 00, and whoever was doing it isn't even credited in the ending theme. I am convinced it was either Ogasawara Arisa (who does Marie/Soma) or Honma Youko. (who does Sumeragi) I pride myself in my ability to recognize seiyuus, yet this I am afraid I might have to admit defeat - but there's no actual info to confirm or deny this. Do we know yet?

I've sat down and listened to the amazing amount of two lines the female Tieria gets to speak, and the pitch rise she does at the second sentence is similar to how Ogasawara does the casual speaking Soma - but not similar to how she voices as Marie. The pitch isn't there from Honma however, she never raises her voice to that kind of pitch, always the calm and sultry voice from Sumeragi. I don't have any previous experience with both of their voices as they're both fairly new and not too much used either, and I haven't seen the shows they've been in. Should I get Wolf's Rain to hear more of Ogasawara, maybe? It's not like I want to even watch Futari wa Precure for more of Honma.

P.S. Marie is awesome.
