That lawyer guy is so annoying, but honestly, I think he will prove relatively harmless. It's the BIL that I don't trust. I highly doubt he was wanting our MC to come look at potential jobs.
I just can't figure out if he is truly just trying to get MC to fall for him, and willing to deceive him so as to take advantage of him, or if he was trying to set him up for a trap laid out by MIL. Either way, I wouldn't trust him as far as I could throw him.
