premise: 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 does n'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 has n't had morphine in several hours . What may be her reason for giggling when she entered Will 's room ?
hypothesis: She was excited to sleep with him .
