I started chapter 4 with 0 points for her, but still couldn't get the 3rd option. Is getting some trust points from her meant to be unavoidable? I seem to get +1 trust no matter what i pick in the Amanda treatment options, also +1 after coming back with Lisa after the talk about the green bag (that's so the birthsday present for MC right) before the storm.Undermine her from the beginning in Ch3, and refuse to make peace after recovering the canister from the docks.
