Or how about people from his same year don't notice that he wasn't actually there.
It kinda happened once when that chick was interviewing to be Louis' associate.
But only once though? Really?
I think the writers will eventually go down that route. I mean his secret is a major part and with litt not trying to take him down (for now) it's going to surface sooner or later again.
The premise of the show is kind of silly when you consider law schools publish a roster of their graduating classes (and some publish incoming classes), top tier schools max out about 200 students and are broken up into smaller groups so SOMEONE would remember seeing you, and almost all top students at Harvard participate in on campus interviewing after their first year so Pearson-Hardman would have a list of the top 10-50% of students from the school. Then there's the whole law journal participation thing.
But then again you could go to school for 3 years, leave the buildings after class every day, never work on a journal, not do on campus interviewing, not intern anywhere, and never talk to anyone. Just take final exams and keep to yourself otherwise. A few clerical errors later and Mike's story is possible. Remind me if they ever covered his LSAT score (or lack thereof) being on file somewhere for 5 years or the fact that he'd have to have passed the bar, submitted an application to practice law in NY, been interviewed by the ethics committee, and then had a public swearing in? I honestly don't remember if it was said that he did/forged all of that?
If so, it's extremely far-fetched, but possible.
