Hinawa is a sense of comfort for Lucas so it would be kinda strange for he to be there imo. I also think that Lucas doesn’t feel guilt towards his mom’s death bcs of the fact he works with a baby drago instead of trying to seek revenge like claus does.

I feel like the reason she wasn’t there is bcs Lucas feels no guilt in hinawa’s death unlike claus and flint. Flint (and Alec) are upset at first that Lucas let claus go on his own and Lucas internalizes this thus why they both appear in tanetane. Just like how duster internalizes wess’ abuse
