"Hold on tight!"
Vanessa knows when it's important to hold on tight. Although I don't think she was around to warn Tucker in this instance, she often reminds herself. And since I know she loves her little cousin oodles and oodles (because of her wonderful patience for him grabbing and pulling her wild hair -- she's not always that kind and understanding with others doing such things), I can only imagine she would've shared her wisdom to "hold on tight".
