Trivia: In The Last of Us (2013) and The Last of Us Remastered, Joel was in his late-40s and had Sara in his late-teens/early-20s. This was confirmed on the official site and other materials.Wanted to come back to this since I read it the other day. I don't think it will be a problem to have Bella look "older" in the second game. She wore a chest binder on this series, and the clothing choice (baggy clothes) was obviously designed to have her look younger overall. Also make up is a huge part. She already looks 19 or 20 in real life appearances:
I'm actually more concerned about Joel's age in the second season. Joel was 51 on the first game and 56 on the second one, however in the series he's already 56. Pedro does not look 56 at all, especially considering the post-apocalyptic nature of the show. If we get a 5 year timeskip, it may be very hard to have him look like he's in his 60s.
The 51 age was a retcon from The Last of Us Part I and II.
