Quick Headcanon
Tam is a major Chicago fan. She doesn’t care what anybody else thinks or says; she grew up listening to eighties music all the time, thanks to her mom, and so her explorations of older music led her to Chicago. And she loves them. She knows almost every word to almost every song.
After the whole incident with the Assassination Tournament, Tam got an e-mail from Wayne Enterprises that had the word “URGENT” in all capital letters in the subject line. She clicked on it, and it took her to a video of Tim playing “Hard to Say I’m Sorry” on the piano.
