Poor thing finally comes out of his shell just to be rejected.
This gutted me.
I really enjoyed his interactions with Janine because he was obviously entertained by her and I think it was beyond him fulfilling his duty of being the Best Man. He wanted JOhn & Mary to have their time together… Molly had her boyfriend, and Lestrade was busy… so he reached out to the only other person at the wedding he felt comofortablish chatting to… but he did the job too well and found her what she wanted for the evening.
I just really wanted to hug him throughout this whole episode. He tried so very hard.
