It's amusing how despite being a side character in the grander scheme of things, we can easily see and know so much about Alicia in this one chapter when it took the other girls so much time.
Even more amusing is that Alicia is quite evidently not in Uncle's harem - she respects him a lot - being a magician herself, she clearly regonizes Uncle's capabilities and memory magic - but that's all it is, respect.
I get the feeling that this we'll see her again, but it'll have to wait until we get more elf-chan and winter-girl chapters.
