April's first instinct when reading the email was no. After the last confrontation she had no desire to return to live under the whim of Vance, and she knew without asking that the same could be said for Eliot and Nate. Especially for Eliot.
Her second reaction was wondering what Vance had done to put them all in danger. She did not doubt that he was speaking the truth, because Vance had no reason to contact them otherwise and if he it was just a matter of wanting them back he had the means to force them.
The question was, how dangerous was extremely unsafe?
Knowing there was nothing she could do right now, April went about her day, taking care of her daughter and preparing dinner while waiting for Eliot to come home. When he did, she wasn't surprised to see that he had brought Nate.
"So what do you make of it?" she asked without preamble. There was no reason to delay this conversation, dinner on the other hand could wait for a little while.
