"No, no, no, let me, I can sit on my own. I only hurt my foot, I'm not crippled" Ellie asked to be freed, not wanting Sydney's help to sit on the couch as they reached home and got into the house.
The crutches were enough help to her, she didn't want to be a burden to anyone because of her hurt foot. She can still do things on her own. She refuses to be treated as if she's kind of useless now.
"Okay, if you insist" Sydney let her go as she wanted. She held her and was guiding her toward the couch so she wouldn't fall, However, Ellie didn't want her help. She has actually been acting this way since they got back from the hospital.
Sydney had even wanted to help her out of the cab when they reached home. But she insisted not to be helped, feeling like she could still do everything on her own. She just pointed it out now too that she only hurt her foot, she wasn't crippled.
