I have a feeling that Ellery has no problem with public displays of affection etc but restrains himself for Ennis' peace of mind. Although how even Ennis can restrain himself even in public having Ellery within grabbing distance is beyond me. I mean just look at him!
Well, Ellery has no problems kissing Ennis hello or goodbye in front of Wes or Alma, Jr. However, he doesn't like public displays of affection either. He told it to Simon. When Ellery receives Ennis's token, he'll probably cry a river, and Ennis is going to blush. So, it'll probably be an uncomfortable situation for both of them if they make the engagement ceremony somthing public or semi public. Perhaps, later on in their lives when Ennis is finally used to his life with a man, they might be able to do something in front of their friends. An anniversary celebration or somthing like that. But now is too soon, IMO.
Jo, thanx for the pic! He's so dreamy *sighs*
