We present early decline spectra of the two Large Magellanic Cloud novae: LMC2004 (YY Dor) and LMC 2009a and discuss their spectral an line profileevolution with special emphasis on the existence and appearance of a sharpcomponent. We show that the narrow component that characterizes the emissionlines in the maximum spectra of nova LMC 2004 originates in the ejecta. TheHeII 4686 A, narrow emission which appears at the onset of the nebular phase inboth novae is somewhat controversial. Our observations suggest that thecorresponding line forming region is physically separated from the rest of theejecta (the broad line region) and environmentally different. However, the lackof late time observations covering the super-soft source (SSS) phase, thepost-SSS phase and the quiescence state does not allow to securely establishany non-ejecta origin/contribution as, instead, in the case of U Sco and KTEri.

On the narrow emission line components of the LMC novae 2004 (YY Dor) and 2009a
