Episode made me want to strangle a puppy...
Spoiler for Spoilers I think? just to be safe.:
This episode made Shion out to be a tramp almost. I mean in her answering arc, it's pretty clear she is not just in love with Satoshi, but
OBSESSED with the guy! I don't think she would forget him that easily just because Keiichi wooed her a bit
But in Meakashi-hen, Shion does point out how 'It wouldn't surprise her if Mion liked Satoshi too since they are twins after all....'
Then Later on in the second volume she says something like, 'Onee really likes this keiichi, I think If I got to know him I'd like him too.'
So I feel like this episode could use this for justification but still, forgetting about satoshi? no...
