Jack chuckled a bit at the Time Lords answer, but surprised with the kiss he recieved to only kiss him properly as well, not long after, watching the Doctor do some funny dance that made him laugh. Seeing the Time Lord a bit wprn from all this, Jack had gotten off the platform to where the Doctor and Arwen are. 
Arwen was watching them goof off and be kids. For some reason, this felt familiar to the red head. Unknown as to how but it just did. Pushing this aside, she watched the Doctor do some funny dance that even made her laugh. Upon the Doctor looking at her, the smile never left her face. "Im glad you had fun, Doctor." She pulled out her phone to realize the time. "Wow. Its 4 already? Hey Jack? Can we go to the ferris wheel?" Arwen asked. 
"Of course we can. Wanna go too Doctor?" Jack asked.
