I'm impressed. Having the poison be revealed as lead at the last minute not only provided a logical contaminate for Lois' symptoms, but it also gives Wendy the means to undo all that unnaturally rapid progression in the 'relationship' of Lois and Clark.

Short term memory loss is a handy way to put the 'toys back in the chest' in exactly the same manner in which they were taken out originally.

What Wendy won't do to make the gentle readers happy.

Tank (who wonders if Clark can get himself some of that lead so he can 'forget')
