I could see Mike doing his own version of the van scene/Will's painting confession in S5 where, because he is a writer, he tells a little story but it's clear to us and Will that the characters are stand-ins for their own relationship and reveals his feelings for Will.
ok so hear me out but I need mike in the upside down calling out for will like how el and will both called for mike (their love interest) while they were in the upside down
jason is saying that chrissy would never buy drugs. the phrase "straight as an arrow" means honest or genuine. it turns out the jason was wrong about chrissy and that she actually was buying drugs, proving that she wasn't exactly how jason thought she was.
now where else have we seen an arrow?
HMMMMMM
i WONDER who we've seen who hasn't been being truthful or honest??? mike's not "as straight as an arrow", he's not what everyone thought he was.
not to mention the arrow was YELLOW.
AND this happened as suzie's house where everything was foreshadowed.
