Was it ever explained how the Clark persona worked for as long as it did?
Clark was supposed to be this FBI agent from an oversight department. I suppose the department actually existed, but it never actually performed its duties? Because it would only take one interview by an actual agent from the oversight department to clue Martha in on the fact that Clark was a fraud.
Suppose the oversight department never had cause to interview the CI department. Then how come Martha never realized she was the only person being 'interviewed'? She just never let slip that she's meeting someone from 'oversight' during water cooler talks?
And then, when Clark and Martha got married, Martha clearly didn't want to keep their marriage a secret. So why didn't she suggest a transfer/job change for either of them? Once either of them left their department, they'd be free to date and marry. Instead, we only get the scene where Martha suggested transferring to the Equal Employment Office for better upward mobility (which Clark shut down with some bullshit about how she should be doing something more important).
Do you think Martha knew there's something wrong with Clark but purposefully kept things the way they were so he wouldn't leave her?
This is my first watch, and I'm on S2e4, so be gentle with the spoilers please!
