i think the most possible to happen is the isse residence member find out they can exchange info with the one inside the seal,

for the option leave the seal is quite hard, in LN 21 maou lucifer said to seal or destroy trihexa is time consuming so they wouldn't come out soon (in 30 years, when EX story began)

for leaving message is also hardly to happen because in EX story azazel himself for devil it hard to have a child also in vol 23 "the upsetting sorcerer" himself said it take too long for him and his wife to have child. more over in the end of EX story the memory of present character including azazel himself is altered/erased
