I think Laura knew Alex was listening ...and I think she played it exceptionally well....

Alex could derive some reasons for his annihilations from their conversation and Laura ensured she wouldn't be one of them by praising his maturity and making it clear she isn't putting him down.

Evelyn however could have made herself a target and she def made Lateysha, Sam and Hughie targets by naming them as the instigatiors of the drama.

I think Laura knew he was there and used the opportunity to her advantage...not sure if Evelyn knew he was there but if she did then good chance she was using the opportunity to put Lateysha, Sam and Hughie in the firing line to save herself.
