what sort of fruit? apple, pear, plum? because only stone fruits will grow well in fans, apples and pears grow well in espaliers.
i'm assuming you mean the main bud at the top of the trunk? if so, the next one down the trunk will take over as the main growing point.
some of the brown buds will grow, and some won't. But you won't know which until later in the year.
