With Lizbet in Eleven's arms, Jane was able to fold up the stroller and lean it against the side of the entryway so it wouldn't get in the way of anyone else who might stop by. Once that was done, she could take in the beauty and wonder that was the TARDIS. It really was so impressive and it showed in her expression as she took in just the entryway.
She turned to smile at him, even as she rolled her eyes. "I know it's totally cliche but...it really is bigger on the inside." That was the way to say it and even Jane wasn't immune to the absolute geekery that was being able to say it for herself. "And maybe we're the ones that need the cheering up, since we missed you." If he didn't want to say he needed it, she'd say she needed it.
"I got a brother and then lost him pretty quick. Kind of puts a downer on things for a little while. But I'd say you're making up for it, with her." Meaning the TARDIS. "I know I need a definite tour, because I'll get lost and never leave, in which case my boyfriend might get worried." She was teasing, of course, but she did want to see the TARDIS from his perspective. "I'm assuming she's been trapped by the Dome as well?" That was a bit sad, but they'd all make the best of it.
Lizbet, for her part, held tightly to the Doctor's finger. Mommy was really sad you were gone. She said you'd be back though.
