Do anda think Simba is able to lift Nala on his back and carry her (like Kovu did with Kiara in Simba's Pride) atau do anda think Nala might be heavy for him?

I think simba could lift Nala he is strong after all

Probably. I don't think she'd be much heavier than Kiara.

I'm pretty sure Simba can do it like 100%. He's strong. If Kovu is younger than Simba and can carry Kiara and Kiara is not that much smaller than her mom then, yeah...Simba can definitely carry Nala. :)
