Celestia’s face is alongside the filly’s now, and Celestia nuzzles the side of her head. The filly’s head twists the other direction, overcompensates, then slowly tilts back to level. Upon discovering this new function, the filly starts tilting her head by small amounts in every direction, returning to level after every adjustment, and opens her eyes again once she’s finished, finding Celestia’s own close eyes easily. The white alicorn then nudges the filly’s front half to the side, pushing the closest leg out with her snout and dragging it out in front of the two of them. The filly looks down at it and slowly, experimentally, flexes the leg.
