That's all the invitation Spencer needs. He gracefully contorts his way inside and finds an opening on the floor, although he doesn't really take personal space into consideration. "What's up, night owls?" Spencer makes sure to smile in the way that best highlights his dimples, even though... it's dark and they probably can't see him very well and being a little extra cute isn't going to make anyone forgive him for the intrusion any faster and... NEVERMIND.
