Minor finale spoilers
The fact that Ross wasn't around when Chandler & Monica announced their engagement was similar to TOW Everbody Finds Out, which was in syndication Sunday night. There, Ross wasn't around when Chandler & Monica first admitted they loved each other. This has the potential to be a cute running gag: everytime something major happens with Chandler and Monica, Ross is never around to enjoy it. (Aside from being periously close to realizing C&M first consumated their relationship in TOW Ross' Wedding.) Imagine Ross not being around for the C&M wedding itself (Ben describes the wedding over a cell phone to his father, as Joey did for Phoebe in TOW Ross' Wedding), and when/if Monica announces she's pregnant (which I predict will happen in the Season 7 fanale or the Season 8 premiere). I also predict Ross grumbling a lot in the Season 7 premiere about how he misses everything important.
