It doesn't fragment it, but sometimes out of respect to your interlocutor it's a good idea to not add another two lines to your emote just to portray something that could have been just as easily expressed with an acceptable abbreviation (Ellipsis, in this case).

When your multi-line emote goes from expressive detail to looking like early-modernist prose, you're just making other roleplayers look at your imitation of James Joyce's writing style.
