In the video, you can see how the band, laughs at the younger versions of them. Alan Ferguson (the director of the video) said in the behind the scenes video that "we're shooting the scene were panics on the boat, this is the new panic, this is 08 (2008). its all most like the new panic is riding the boat and laughing at the old panic who kind of new and all washed up, it's like saying goodbye to the old and hello to the new."
so I think the song about panics change over the years. And that in the scene were half their bodies kind of pop off and the kids come out, it's like saying that, the younger(kid) versions of them are still in there but they will kind of always be the same
All of this kind of feeds into "things have changed for me and that's ok, I feel the same, I'm on my way." things have changed for panic, but it's ok, they don't feel any different because they will always be panic (kind of) in their hearts and their on their way to keep making more music etc.
also, there are things like "things are shaping up to be pretty odd" that kind of means they never knew they would become famous etc
I hope this was helpful bye
