Clark goes into hiding after he discovers a startling new power that quickly gets out of control and accidentally harms Lana. However, after a hot new teacher uses kryptonite-enhanced pheromones to convince Lex to marry her and then spellbinds Jonathan. Now Clark must get a grip on his new power in time to keep Jonathan from killing Lex before it's too late. Despite Clark getting a new super power, which he sometimes uses impulsively, this episode was not that great. Naturally, they have to do something seductive (and perhaps a bit silly) with the substitute teacher, who is, of course, Lex's wife.
