  We present early decline spectra of the two Large Magellanic Cloud novae: LMC
2004 (YY Dor) and LMC 2009a and discuss their spectral an line profile
evolution with special emphasis on the existence and appearance of a sharp
component. We show that the narrow component that characterizes the emission
lines in the maximum spectra of nova LMC 2004 originates in the ejecta. The
HeII 4686 A, narrow emission which appears at the onset of the nebular phase in
both novae is somewhat controversial. Our observations suggest that the
corresponding line forming region is physically separated from the rest of the
ejecta (the broad line region) and environmentally different. However, the lack
of late time observations covering the super-soft source (SSS) phase, the
post-SSS phase and the quiescence state does not allow to securely establish
any non-ejecta origin/contribution as, instead, in the case of U Sco and KT
Eri.
