I agree, they could just show him meeting Suzana in the series, just like in that HoM Civil War and Lorna could appear later on another movie or series, something similar to Peter Maximoff or even Emma´s Lorna and later them both find out they are related.
Yes I saw that headpiece and it was more significant because she made it from what her dad left for her, headpieces can be a good thing and not goofy if the story justifies their presence in the story and they look good on them.On another topic: I think Lorna on Gifted wearing her headpiece paved the way for Wanda wearing hers on Wandavision.
My memory of past discussions was people saying MCU Wanda should never have the headpiece because it would look "too goofy" and out of place in live action. Helmets, sure, but idea seemed to be that a headpiece would look weird and made no sense cause it served no purpose. But I think seeing Emma Dumont wearing Lorna's headpiece, and the fan buzz about it even in the state Gifted season 2 was in, really brought some people around to the idea of headpieces in turn allowing Wanda to get hers in Wandavision.
