In the hospital, hours after being sent back to the past Jowd tries to find his footing.
In the last few hours Lynne had died multiple times, learned about the existence of ghosts, had to face the reality she had shot and killed a man—only to not have, desperately tried to save her hero and the father of her ward, found out her ward of five years, her sister in all but blood, had been kidnapped and killed at least once, been sucker punched by the ridiculous reason Jowd had confessed to a crime he didn’t do, stand face to face with her mentor's broken, bleeding form, and now was rushing off to try and save Kamila.
So yes, she was a mess, terrified, exhausted, and most of all, angry.
And Jowd, being the suicidal man he was, just had to point it out.
Or,
someone needed to yell at Jowd for everything he did, the time between them rushing off to save Kamila and Jowd calling Sissel was a perfect time, and Lynne deserved to have a breakdown, as a treat.
