So, on this relatively new decentralized DT system, mr.relax can be kicked out of DT2 without having Buchi-88 to remove him from his trust list, you just need more DT members exclude him [~mr.relax].
I thought that this rule stands only for DT1. Thanks for correcting me (I'll edit now the other post too).
Then it was even easier. Indeed, this guy is no longer DT2. Problem solved.
