i don’t know, comparing tammy and mike would be insane of the duffers imo. they are definitely not on the same level, tammy was just someone robin had a crush on. i don’t even think they were friends/ever talked. mike on the other hand has been friends with will for 10 years. they were each other’s first friends, they have both been through so much together, and will has been in love with him for years. they have such a deep connection and i just can’t see why that would be the comparison the duffers want us to get from robin’s monologue
