She’s not being cold, she’s in shock and denial. Plus she’s faked her death on a boat before, so she has hope that something similar could have happened. Haven’t you heard of the five stages of grief?
No I haven't. Bue
The five stages of grief are Denial (she hasn’t actually accepted that they’re dead and I’d holding out hope that they’re somehow safe), Anger, Bargaining, Depression, and Acceptance. She’s still at stage one so she’s not treating it as if they’re actually dead because she still has hope.
Too cold of a reaction from a mother who might have potentially lost her only son for whom she claims her whole life is about.
