Dr Who?

***Disclaimer: I have yet to really sit and watch this amazing show, I have seen bits and pieces including older Who seasons. A lot of what I have seen was out of order and in patches. The Doctor, I was looking for him. Even standing in a bathroom looking for matches to light random pale green candles. I kept pulling cotton swabs before I found any matches. Someone tries to get into the room, but I start leaving and end up in a living room. I found him (10th) going between rooms rather excited about something. While I start doing something else (I think gathering pieces for I don't know what) he comes back asking if I'm coming. I run after him after grabbing some sort of bag of things. We end up crashing a wedding party. I am not one to judge, but the woman struck me as being a monster- like a physical monster (she had a great personality tho). Some got angry with us and tried to throw us out. But I kept chasing him. He seemed so lonely and I kept thinking "you really are not alone" that poor man was looking for his soul mate. I haven't watched DW in a couple weeks and there really wasn't anything to trigger that. So I wonder, who was so lonely that their whole being was sad for not having their other half?
