||Season 2 Ep40. When Trudy tried to
kill herself she took sleeping pills from Dal's bag. Dal really beat
himself up about it for days. He kept reminding himself how his parents
were always so careful, always keeping medicines locked up.
So it's almost inconceivable that when KC needs something to make
all the competitor's rats sleepy, so that his own rat will win the
race, he finds Dal's medicine box unlocked.
Sure, KC could pick a lock, but I just don't buy that Dal would forget
lessons learned when Trudy nearly died.
