I know it might seem like a stretch to assume this was intentional.
However, I do find it interesting that this score plays while Mike reunites with El at the airport in 4x02, only for it to cut out instantly afterwards as Mike is reuniting with Will.
And in the scene in 2x01, outside of the middle school, Mike is annoyed with the other three over their interest in Max. This same score then creeps in as the boys look at each other, before they start running curiously towards whatever Max threw in the garbage, and with Mike running after them. While the score continues, Mike waves along with the other boys as a few girls walk passed them.
Basically the only parallel I can find between these two scenes is Mike waving awkwardly at girls…
i was obsessed with them when i was 8 and i am still obsessed with them now
