In the thread I responded too you said Silviana said one woman would do to shield Egwene, which she did not say.

Katerine complains that she must go while Egwene is still on Forkroot. Note they shielded her in shifts all night long, with two women, which Katerine doesn't complain about, just her personal involvement. Basically Katerine is trying to say "she's half dead from Forkroot, why do I need to escort her to her bed and waste more of my time when at this point Beresine alone can clearly manage it".

I don't know how you think this reinforces your point that one woman alone could hold Egwene's shield. The entire time (except the 5 minutes with Silviana) Egwene is captive she has two holding it even when she's on Forkroot!

I don't understand what you are arguing here... it seems very obvious that Egwene cannot be reliably held by 1 AS unless she's as strong as Romanda/Lelaine. If Amys can't hold it for more than a few minutes I very much doubt any AS below Sheriam could.
