I think the master probably showed up to Jo Grant's wedding in a paper thing disguise and when asked who he was answered 'oh let's just say I'm... An old friend'. When Jo was like 'i know it's you' he was like 'nooo you don't'
Everyone from UNIT wanted to kick him out but Jo was like no leave him be you'll ruin the reception so they just watched him suspiciously all day waiting for him to start shit but he never did.
