On Thursday's episode, the pair will kiss again and finally explore a relationship, but Mike quickly learns that his major lie of not owning a law degree will get in the way.
"Rachel isn't made aware of what his story is," Adams tells TVGuide.com. "Mike's the kind of guy who has a difficult time basing an important a relationship in his life on a lie, so that's going to make it difficult for them to be together in a way they both want to be."
Also in the interview below, co-star Gabriel Macht addresses the possible romantic history between his character Harvey and his executive assistant Donna (Sarah Rafferty). Plus: Adams and Macht go head-to-head in answering TVGuide.com's set of hard-hitting questions about each other!
