The reason babygirl Lisa grinds my gears so much is specifically because she claims that she has done "sooooo much" to learn about the culture... umm. no!!! you haven't!!!
Even though Angela is a BAD person, she learned the culture, she learned the customs, she even learned some of the language ffs. I was watching the marathon they had on all day and got to see Avery and Omar and was further reminded of why i dislike Lisa so much. Yes Avery is naive about some things, but she learned a new culture, new religion, was SO happy just to get a ring that was made in Syria because now she has something from Omar's home country...just put in some effort.
He is from Mauritius originally which is a small island off the east coast of Madagascar, so I imagine there is a lot of paperwork for him to do to become an Australian citizen first if he is not already.
