Oh yes I think that could be the case here. It is very possible that she might have went out to help out the people dealing with the odd futuristic looking Pokémon somewhere else.

(Isa knows very well how often Luisa is willing to put her own well-being aside to assist those in need. It was already expected of every single Madrigal to look out for others but it doesn’t have to come at the high cost of wearing themselves thing over time.

She can just hope that Luisa was safe while helping somebody out there with those futuristic Pokémon running amok.)
