Clear side image attributes

[rames44]

I have a character with a variety of side images:
side paul
side paul confused
side paul angry
side paul sad

If I use a sequence like:

Code: Select all

paul confused "What's going on?"
peter "Good stuff"
paul "OK"

I get the correct "confused" side image for Paul on the first line, but then on the third line, I still get the "confused" side image. What I'd like is to revert to the image without any attributes.

I can do that by saying

Code: Select all

paul neutral "OK"

because there is no image with "neutral" attribute, but then "lint" complains.

Is there a way to force Ren'py to clear image attributes so that I get what I'm looking for? Or, if I use attributes, can I not use an attribute-less side image?
