Narrative:

Passenger was upset because his itinerary and his seat assignment were not the same. #4 flight attendant spoke with him and handled it. Flight attendant #4 and I were at 2R door. The passenger moved to xx which was according to itinerary; not his boarding pass. I went in first class to resume duties. After safety demonstration; during compliance check; flight attendant #2 overheard passenger say 'I'm going to kill someone.' she came up to 1L and told flight attendant #1 and flight attendant #2 called cockpit and told them. We went back to the gate. During taxi back to gate; #2 flight attendant and I changed jumpseats so she could be up front when first class door was re-opened to talk with ground personnel and police. I stayed at 4L/right to monitor each cabin. As I was all the way in the back; I have no idea of series of events with ground personnel; passenger or police. Passenger was removed. Flight attendant #2 and I went back to assigned jumpseat for second taxi out and flight.
