...Honestly, the author handled that far better than i was expecting. Lugh managed to turn her down, but in a way that left her understanding exactly what she was asking of him. I was worried about Talt getting her feelings hurt (that one panel on p.17 made me almost wish Lugh would go through with it, just to reaffirm her self esteem) but Lugh managed to weave his way through all the pitfalls and let her down gently.
With this, however, Lugh can't really keep treating the girls as little kids anymore. No one can remain the same, however, and not all change is bad. Even Lugh has grown tremendously over the years; ask yourself this, if it had been the old Lugh that Talt propositioned, the one that had just crossed over, would he have held back to avoid hurting her? Or would he have seen it as a good opportunity to create an effective asset, and thrown young Talt onto a bed without a shred of guilt?
Also, how often does he see it that Lugh can recognize his mother's negligee? What kind of genre are we in right now? (As if the H-doujins didn't practically write themselves at this point)
