Holly's Team
Holly is a believer in honesty; when she took her team aside, she told them what had happened and everything that she knew, including the fact that it was Clem's powers that had malfunctioned/gotten out of her control. She was very clear that this was an accident, and that as always, her team were not to indulge in spreading gossip or rumour.
She was also very clear that this was a shock to everyone, Darcy was one of them and even though this is a tragedy, she does not blame Clem - and she does not expect her team to either. She'd reassure them that appropriate measures have been taken to help Clem and to stops this from happening again, but that she wants everyone to be vigilant and come to her the moment they feel something is out of kilter with their own powers.
Holly would say that every single member of her team has to go and see the psychiatrists - if they're not already there - to get grief counselling and that her office door is open. She also made a point of having an all-team dinner - which she attended - to allow them a chance to grieve together before they moved to handle it in their own way.
