As an aside, I've see the music talent that Boston has to offer (the Warblers are from Tufts Uni. a Boston school) and they are not anything special; above average I would say. Go down to Newbury St. and see some of the Berkley kids perform for some true up and coming talent. Reckon I do have a small bias because I dated an opera singer from there and he would croon for me (no further emphasis without me going into horny school girl mode). Hell, I have even seen Wheelock College put on a decent rendition of The Rite of Spring with the ballet.
As I have said, I don't have any particular problem with Darren Criss as a singer/actor at all (his range is not that good compared to Colfer though). My problem is that Chris Colfer and him have little chemistry on set so it is not really a believable couple.
I've been on a few dates with a guy that I fancy a bit and we hold hands, hug, kiss and what not. I haven't told him I loved him yet but if and when I do (or he does), I am positive that a kiss would follow if it is reciprocated. You don't profess your love to someone without some follow up like a kiss or even an embrace.
