May have an idea Where Lee has come from apart from being hired as handy man, What if Lee is the second part of Shirley's Plan to try and seduce Melinda to try snd drive a wedge between Daniel and melinda though Daniel's jealousy ( Just a quick thought) could be a way to link Part V2 to V1
My guess, he is more like a guy from another clan (yakudza like) so his role to scout Williams territory and business while William is away on medical leave. Lee tries to infiltrate into his family by spying and fucking females there right and left .
Same time, Daniel being hostile to Lee and spying on him will likely discover and prevent something by saving Williams business or family member, which will result in promotion and some award from Willam, like teaming (DP) Melinda with him

Anyway, this game is ruled by women so don’t try to look it from male perspective
