I get the feeling Louis is getting scammed by the architect..
Like, she is some con-man well, woman, like she'll say one episode that that guy she's been in an open relationship with is in trouble some way, and Louis has to help etc.
I dont know how it would make sense, considering he contacted her in the first place, but idk
I think it's just from where, like, if theres not something else going on, then what is the point of the whole subplot? Just pointless filler thats not going anywhere maybe?
