Headcanon: When T'pol learns about Sarek’s and Amanda’s relationship, she reaches out to them- Amanda in particular. When Amanda is struggling adjusting to a new planet with new people, T'pol sits her down with tea and tells stories about her time on the Enterprise (as well as some failed attempts to retell some of Trip’s dumb jokes- which still manages to comfort the young human woman). When people talk against the union of the vulcan and the human, T'pol defends them- T'pol does everything in her power to protect these two.
When baby Spock is born, T'pol is the first to congratulate them
despite congratulations being somewhat illogical
