At the end of episode 220 of _Detective Conan_ , "The Client Full of Lies",
Heiji appears and explains the reason behind the fake name "Reiko" to Conan
that it was to conceal the fact that his mom is from Osaka.

But that doesn't explain why she has to lie about her being good at cooking
and her allergy to dust. If she were to hide her identity, she need not lie
about the cooking and the allergies. Conan wouldn't be able to find out even
if he knew that she was from Osaka since it was his first time meeting Heiji's
mother.

Why did she have to go that far? Or was it part of her test for Mouri to
figure out her real identity?

Even if it's the case, I bet no one's going to be able to deduce that she is
Heiji's mother because first, it's impossible to even know the true identity
of a person just by knowing her hobbies or skills. Unless she has a
distinctive quality in which the Hattori's are famous for.

Second, Conan did not even know a thing about Heiji's mom. The test was
actually for Shinichi but since he wasn't there, she tried Mouri instead. No
matter how good Conan's deductions were, it was impossible for him to expose
her real identity as Heiji's mom and her real intentions. They were even
surprised when she revealed her true identity as Heiji's mom since Heiji
didn't even look like her.

So, why did she have to lie about all the stuff?

Why did Heiji's mom have to lie to Mouri and Conan in episode 220?


Her first three lie about her cooking skill, allergies, and the fact that she
is married was intended from her to test Mouri whether he noticed it or not,
not to hide her real identity as Heiji's mother. But her third lie came
unintentionally from her when she was about to say cold coffee. Maybe she did
it accidentally and has to cover it with saying "Reiko".

So she lied to test Mouri, not to hide her real identity.

Another possibility is maybe she didn't know whether Heiji told his friend
about her hobby and others or not, and she did that because she didn't want to
know that she is Heiji's mother and make all her lies vain.
