Haha thanks! We are both officially oooold!!
So Alex had been kidnapped, but escaped, right?
Correct. Were other students kidnapped as well?
Yes. Were they being held on school grounds?
Yope, there is an FA-ish assumption lurking. Locked up in a room? Sports hall?
No. Had he been kidnapped by a teacher? More than one?
Yope. Were the criminal(s) making demands in exchange for the students' release?
No. Did the teacher(s) only apply for the teaching job because it was part of their criminal plan all along?
No, FA. Was the crime well-publicised?
Irr. Did Alex believe that his sister would know of it? That his parents would?
Possibly, irr. android18
Was seeing his sister with the man enough for Alex to deduce that his parents weren't home?
Yesish. Does he go home specifically to find his parents?
Yes. Does he believe they'd keep him safe?
Irr. Does he believe that his parents have died?
No. Been attacked or killed by the kidnapper?
No.
