I need to post as well, but I'm thinking of doing that tomorrow and officially add Diarmuid to the scene (though he can be considered already there) as well as have Atalanta bust Medea's identity on the spot, just because no Argonaut worthy their salt would forget Medea. At least as far as I've seen Atalanta and Medea have no bad blood running between them, so it shouldn't get sparks flying immediately.
I think Diarmuid will introduce himself to his master by name as well, since it's in character with his knightly duties and very much like bust Cu Chulain because of Gae Bold. Over all, I'm really looking forward for the interactions between those Servants, but I'll keep to a posting rhythm I'm more used to instead of rushing blindly. Apologies if I'll be holding back anyone for the next 12ish hours or so.
