Didn't it make you feel just a little bad that Tom screamed, "LET ME LIVE!" over and over while Barnabas was destroying him? That really got to me.
As for the question posed here, Randall's staking of his sister was emotionally upsetting for me. To Barnabas, Tom was pretty much a stranger, but Randall was forced to destroy his own beloved sister, and his excruciating pain was all over his face and in his actions, a superb performance that was hard to watch.
Love, Robin
