If an Aes Sedai links with other Aes Sedai, will or can the others then sense if she is bonded? Also, can an Aes Sedai (at least as far as the Tower knows) ‘unbond’ a Warder? It’s been suggested that they will set a man free/release him if he really wants to leave, but does that mean ‘unbond’ him or simply ‘not pursue’ him and release him from whatever oaths he’s sworn as a Warder?
No. They can’t sense it. I think you may be thinking about an adaption of bonds.
