It’s Lyle who expertly reminds Todd of his criminal past when Todd joins Margaret’s firm. Lyle’s takedown is so subtly elegant you may not even realize it was a roast if you weren’t paying close enough attention!
Fastidious to a fault, Lyle is understandably annoyed by Todd — after all, while Lyle plays by the rules when it comes to private investigations, Todd is willing to bend them time and time again (hence why he ended up in legal trouble in the first place).
