According to the Bible, none... All 12 partook of the emblems. Jesus told them to partake even thought they were not anointed with Holy Spirit yet.
They were anointed at Pentecost...
And Judas was present too according to luke 22:21.. Watchtower says that luke's chronological order is wrong.
This is what they say according to Insight on the Scriptures under Judas:
"Immediately Judas left the group. A comparison of Matthew 26:20-29 with John 13:21-30 indicates that he departed before Jesus instituted the celebration of the Lord’s Evening Meal. Luke’s presentation of this incident evidently is not in strict chronological order, for Judas had definitely left by the time Christ commended the group for having stuck with him; that would not fit Judas, nor would he have been taken into the “covenant . . . for a kingdom.”— Lu 22:19-30 ."
So, whom should I believe? Luke was a Holy Spirit inspired writer. FDS is Holy Spirit guided ( which SO many times that spirit has been proven wrong)
