It's part of Will's plan to drive his parents crazy . She manages to hold in the giggle until she's safe in Will's room , door closed , her back pressed against it . She covers her mouth with her hand but Will still wakes up , giving her a sleepy smile that makes her forget he's sick . He doesn't say anything , just quirks an eyebrow at her and she bounces across the room , into the bed . Carefully because he hurts more now than he did when she met him just two weeks ago and he hasn't had morphine in several hours .
What may be her reason for giggling when she entered Will's room ?
