Anyone have a weird/odd vibe interview work out for them?

I've been interviewing for this Job, at a huge tech company, which im very qualified for.. I am on my 3rd round. Had another interview this morning with the normal guy ive been interviewing with and his boss. I am a top 2 contender. The guy ive been interviewing with you can tell really likes me. This morning during my interview his boss, was EXTREMELY QUITE. I thought I nailed 90% of the questions. They told me they had another call right after this one so, I knew they were on a hard stop right at the hour mark. Well with still more than 15 minutes left in the 30 minute interview, the boss guy interrupts me and says "hey what time is this over?" to the guy asking the questions.They guy says, we still have 15 minutes.. "Oh okay" the boss guy responds. It was so weird. The boss guy never asked me a single question.. The guy asking the question said to boss guy " do you have any questions for her?" he responds no. Then at the end, they did hard stop about 5 minutes prior and the interviewer guy says "thanks, well be in touch either way".. Am I over-analyzing here or does that seem like that went south to me? All of my interactions have been really positive until we got to that guy. So positive that I'm a second contender for the position. Its just weird that that boss guy seemed uninterested from the VERY beginning and throughout the whole interview.. Is there a possibility he could just be like that? Have you all ever had an interview you thought was weird and then ended up getting the job?
