i really, really love this, because while i love sollux/aradia, so often i see fanworks depict aradia as jealous or depressed over his relationship with feferi when i don’t think she would be either of those things at all.
even when dead, aradia made it clear that she just wanted sollux to be happy. i believe that whether she was pale or flushed for him she would want him to move on. she wouldn’t want him dwelling on her death and letting it eat at him, because no matter what she had gone through, from death to sprite to robot, it was absolutely clear how much she still cared. and i think she cares enough about sollux to be happy for him and feferi. it’s what she would want to see- sollux finally happy with himself again. i don’t think it’d be like aradia to respond with anger or jealousy. she’d react just like this, thanking feferi for helping him and being there for him when she could not.
