will's "you don't get it. i've survived this. the upside down knows me." having such a similar ring to nico's internal monologue in chapter one ("someone has to go into tartarus. someone has to die. nico is more than up to the task." and "he’s the only one who’s capable (even though he’s weaker now than he’s ever been), the only one who knows how to navigate it (even though he got captured), the only one who deserves to face this atrocity.") + will being angry at mike for following him just like nico was mad at jason for catching him in his fall, both nico and will (byers) wanting to protect mike and jason; both jason and mike refusing to let them face the horrors of tartarus and the upside down alone (mike's "i wasn't just going to leave you alone in the upside down again!" and jason's internal monologue in ch2 where he sees that nico is surrendering himself to tartarus again and refuses to let it happen, wants to protect him)...... i'm gnawing at the bars of my enclosure THIS IS MY NICHEEEEEEE
(several people in the fancomic's comment section are paralleling it with percabeth falling into tartarus meanwhile i'm like WELL NO THIS IS MORE SPECIFICALLY JASICO FALLING INTO TARTARUS BECAUSE BOTH WILL B. AND NICO WERE IN TARTARUS/THE UPSIDE DOWN BEFORE AND WERE STUBBORN ON GOING THERE AGAIN ALONE TO PROTECT THEIR LOVED ONES!!! but no one will understand my references...)
