Hmm, i'm pretty sure that one comes from Jeremy too. It's just not spelt out specifically -- Jeremy has single text variant for any sex Lena had at the club (except for Axel who gets custom phrase about Lena's ex) While that generic variant doesn't delve into specifics, since that'd be extra work, i think we can sort of presume either Jeremy does tell Ian some more details during that talk, or EK simply slipped and didn't remember that Mike wasn't outright named.he also knew Lena was cheating on him with Mike in one of his monologues at the beach. No, Jeremy didn't rat out Mike, but Ian caught the wind.
