Cleansing himself after being stunned is probably at least in line with his film character. He had several stunning moments in EP5 that probably required a change of pants:
1. Ambushed by Wampa
2. Seeing Dak's dead body
3. Dark surprise in the Force tree
4. X-wing swamp extraction
5. Loss of hand
6. Family reunion
