Whilst it's uncertain if Simba and Nala definitely went all the way in the jungle, they were reaching certain bases and were happy about getting there. When the lighting is so perfect and there's music and fireflies... Well, let's just say that baby lion at the end didn't just get magicked into existence. No matter what went down, they definitely needed and wanted to be alone. They hadn't seen each other for years and wanted to fully catch up with each other's lives... and bodies. So whilst all of this is going on, what are Timone and Pumbaa doing? Oh, that's right, they're spying on them. They're probably the only peeping Toms who actually cry at what they see.
