Journey To Babel?
1. Sarek has two debilitating episodes which he keeps secret from everyone including his wife, first one with bad timing when the Tellarite was murdered, and the second with witnesses which proves his story and his innocence.
2. Spock deserts his father's operation, then his command post with Kirk's trickery.
3. The intruder ship attacked the Enterprise full of Ambassadors, but the alien identity was unknown, so, who to war upon? Maybe each other.
4. After disabling the intruder ship, Kirk was ready to offer assistance, but instead, the enemy self-destructed.
5. Amanda is the lady who wants Spock to give up command and help Sarek.
