This is how Ryan meets Rapunzel and Ryan absorbs her abilities goes in Thomas', Crash's and Ryan's Adventures of Tangled.
[Ryan and the gang walks in a meadow]
Ryan F-Freeman: Ok. I think someone took the child somewhere. Be on guard, Autobots. We don't want Thomas and Twilight get killed by thugs and Decepticons.
Evil Ryan: [laughs] At ease, Ryan. I can sense the flower's healing powers a mile away.
Crash Bandicoot: Yeah. I hope those vines are...[puts his hand through them] Huh? I found a secret path.
Ryan F-Freeman: A tower? Guys. You can stay on ground and out of sight.
Twilight Sparkle: Yes, Ryan. Why?
Ryan F-Freeman: I want to make sure you and Thomas are not spotted.
Sci-Rianna: Before you do, Ryan. Maybe I can dress you up so you can meet Rapunzel.
[Ryan hides behind a bush and comes out wearing his Rapunzel outfit]
Ryan F-Freeman: Ta da! How do I look, guys?
Aria Blaze: You look like a male version of Rapunzel, Ryan.
[Ryan climbs up the tower and goes to a room]
Ryan F-Freeman: Nice place. I could see that I can live here.
Unknown voice: I know why you're here. And. I'm not afraid of you.
Ryan F-Freeman: Huh? Looks like I'm not alone.
Rapunzel: Who are you and how did you find me?
Ryan F-Freeman: I may not know who you are or how I found you. Need I must say... Hello. I am... uhhh.. Ryapunzel. Nice to meet you, m'lady.
Rapunzel: Rapunzel. You are my brother?
Ryan F-Freeman: Yeah.
Rapunzel: Oh. Do you think you are my brother?
Ryan F-Freeman: Yes. I am happy to see you, sister. [hugs Rapunzel]
