The biggest change will come from the relationship between Hope and Scott, clearly during these years they have bonded closely with the Pym family what with Cassie considering Hank and Janet 'grandparent' figures and everyone having family dinner ect. Also Scott and Hope are an active part of one another's life and are incredibly close currently. This is a bit of a stark difference as I've previously played them very on/off again. Especially given I do a lot of comic blending in most of my MCU characters and Hope has always been a Strong Independent Woman™ that don't need no Scott.
This will be the only sort of aspect to Canon Blending I will likely carry over. Cause Scott and Hope were pure love in Quantumania and I can't take that away from them.
Not TOO MUCH ELSE really needs to be blended currently. Because this all took place in the Quantum Realm it was very single line affected. It mostly affects character interactions between Cassies, Hopes, Hanks, and Janets. This could change depending on the consequences of the actions of Scott's "killing" of Kang in further MCU releases.
Because I mostly played Cassie of YA origins Quantumania doesn't alter how I play her too much unless I'm playing more into the MCU which I likely may do for a while. Especially since there's still the potential of a YA MCU aspect. In this case she will default to just after Quantumania especially when interacting with other Scotts from the Citadel of Scotts™, Hopes, and Pyms.
