[No problem! <3]
It was Pinkie Pie's job to be happy. If no one else was going to try and stay positive about this scary town, Pinkie knew it was her duty as the pony of laughter to try and be happy. It left Pinkie wondering how people would react if she was instead a pony and wasn't changed into this human form. She also wondered what some of the people in this town would look like as ponies. Robert's cutie mark would probably be a beaker, and Rosalind's would probably be a Bunsen burning - just for their passion and skills with science.
"Or from multiple points in times." She replied, still excited about the tenth dimension and what it might have to do with this town. "There's just so many wild options in the tenth dimension. Could you imagine if you don't like one outcome, you just take another path to something completely different - a completely different world, and a completely different you!" Puffing out her cheeks, she had to tell herself to calm down. Rocking the heels of her shoes, she gave Robert a sheepish little grin. "Your work seems completely fascinating."
When Robert moved closer to Pinkie, she stopped rocking on her heels, and looked at him with rapt attention. "You better be. I don't any of us can afford to lose you and your sister. You two seem to be making the most progress here." She placed a gentle hand on his forearm, "But, if you have to go to the hospital to test your new device, I guess all I can ask if that you be careful." Biting down on her bottom lip, she worried about people here. This place was so unpredictable, and anything could be roaming out there. She didn't like to think of people dying for the sake of answers.
