"Support conversations can be accessed between chapters after high enough levels of Support Points are gathered between pairs of units. Support Points can be earned when two units work together to defeat an enemy, and by having units Team Up."

"There are three ranks of support - Rank C, Rank B and Rank A. Support conversations can be accessed between chapters or before the start of a battle, and any conversations that have already been viewed may be seen again."

(I haven't worked out the Team Up system yet. Expect it to come sometime soon.)
