Izzy is relieved she didn't cross at the crossing point, and she nods to Des as the younger woman joins her, pleased to see her taking the sensible option. However, she can't avoid a vague sense of guilt and worry for Leo as she witnesses him drop to the floor in much the same way that she did previously. She joins him and Jordan on the other side of the road as they make their way over.
"You okay?" She doesn't ask what precisely he saw. Though the reason for her own feeling of guilt is already known by everyone else (they were there, after all), Izzy isn't about to be nosy and uncover something that's personal to her colleague and friend. Best leave it for him to say, if he wants to. But she can still support him regardless.
She murmurs to him as an aside, while they wait for the others.
"If you want to talk about what you saw, then I'm happy to listen. No judgement. But, no pressure, okay?"
