Sc. 2.
"As you like this give me the lie another time."
Perhaps for 'As' we should read An.
"Trin. Wilt come? I'll follow, Stephano."
The first sentence here belongs, I think, to Stephano's last speech. See on As You Like it, ii. 1.
Sc. 3.
"If I should say I saw such islanders."
The folio has 'islands.' So in the Queen of Corinth (iii. 1), "Our neighbour islands would make of us." In both places sense and metre alike require islanders.
