this is not from episode 8 and i cant remember this
from any other scen in the anime...that this ever showed up >.>

*It is* from episode 8, between 18 minutes, 15 seconds, and 18 minutes, 18 seconds (someone constructed the picture from multiple frames). It's when Sia and Rin are trying to find a restaurant for lunch, can't find any, and end up in a family restaurant. Then, we see Rin, waiting for Sia, and Sia, in the toilets, talking about her "shoubu pantsu" ^_^;
