ICYMI: In the FD press conference, their answer to "what's next?" was basically "we'll see".

Earlier on, they talked about how difficult this season had been for them (dealing with injuries etc.) and how happy they are to end it with a very good performance and a podium placement.
Personally, I choose not to read too much into their answers. I don't think they have had the time to process things yet. I mean, to get through this season you'd think their mindset was something like "gotta be ready for Olys and focus and stay in the moment" and then "gotta be ready for Worlds and focus and stay in the moment", as opposed to "let's sit around and re-evaluate our life and career goals and spend time and mental energy thinking about what we're gonna do
after this season before we've even finished this season". And then right after the last competition of the Olympic season is finally over, they get in front of the press and immediately get quizzed about their future plans... It might take a while before
they know what their future plans are like and that's 100% fine.
