Robbie enlists Jane to help uncover Cathal's plans, however it backfires.... in a big way. Elsewhere, tensions among the O'Briens result in yet another family rift, while Eamon gets caught up in Pete and Bob's war. Also tonight, Damien insists to Laura and Dean that he can make it work with Caoimhe despite their mixed opinions. Sigh. The denial is strong in that one.
