"Have everything set up here to be taken care of while I am with you after the surgery. Hope everything goes as scheduled. Talked to (D18) and we have agreed that between me, her, (D16) and (S10) we can handle whatever comes up next week so you can concentrate on your recovery." I would try not to read too much into this right now...everyone is in an emotional state right now...keep calm. Sounds like they just want to help W...not an affront to you.
