THAT IS ANNOYING. though i feel like since will's not actually a part of their relationship (yet) he wouldn't see as much of the gradual progression of it, like he wouldn't know the exact night she first spent the night, when they first started showering together, he would just see that they are super, super close, and i feel like even in the very beginning, before all the STUFF STARTS HAPPENING they would still be spending a lot of time together, more so than with any of the others, so i still think it's conceivable that they start out kind of attached at the hip and then become SUPER attached at the hip, and will can still be like "WTF???"

and especially if ben is off training for the first month or so of filming and he comes back and thinks "hmm, this is kind of new" but also not really because they have always kind of been like that, and he has no idea that this has all possibly developed over the last month (or so), so he is kind of the worst person to ask because he hasn't been there, and will thinks that he is legit going crazy, because surely they weren't like this a month ago. except for they kind of were. possibly.
