Sidonia: You'll have some peace and quietness,
Lambik dear. I'll make coffee and cake...
Sidonia: You can't get any cosier than that.
Sidonia: WHAAAA!
Sidonia: The secret one!! He's inside!!!
Wiske: Well well. Who started this subject? I'm
not saying anything!
Lambik: Jerom, take Sidonia inside! I'll handle
this!
Secret one: I believe Sidonia was a bit frightened. I
suspected that this would happen so I've
made the foot-bath ready.
Lambik: Who are you? How did you get inside? What
are you doing here?
Secret one: No questions please. Just sit down.
Secret one: I don't want to harm you. I'm only here
with the best intentions!
Lambik: Dare say! And we should believe that...
Show us your face!
Secret one: I cannot do that and I won't do that!
Now listen to what I'm about to say!
Secret one: I've been following you for a long time!
Wiske: I'm not saying anything!
