Are you talking about the 'Forget' mind meld Spock did for Kirk in "REQUIEM FOR METHUSELAH"?Well, Picard obviously had some unresolved issues from TBOBW and we had that episode 'Family', which was new territory for Star Trek.
Wouldn't it have been cool if his mental anguish after these horrendous experiences was resolved by some 24th Century techniques. Maybe a telepath could help him, like Spock did with Kirk in This Side of Paradise.
