I think Hughie's mom may have given his dad the V b/c we saw a blue liquid go thru his IV at the end of the episode. I dunno about Butcher since S5 of the show has been confirmed and is the final one. Kimiko saw how Frenchie felt about Colin, I think they've always had more of a brother/sister 'love' dynamic, plus she's got a metric ton of things to work through herself i.e. the Shining Light, so I think the last thing she wants is to get romantically involved w/ anyone...
