It's the colony's founding day. Josh asks dad Jim to check up on Boylan, whom commander Taylor grills mercilessly about the Sixers' mole, then uses a truth serum overdose. Thus Jim hears about a secret buried under the pilgrims tree, which Malcolm knows to be Taylor's alleged first home as colony founder. There Jim finds a corpse, which misses an arm, just like missing general Philbrick. Meanwhile a smashed giant dragonfly is found to be chip-bugged by the Sixers. Malcolm repairs it to trace their mole's communication line. When it enters the Shannon home, Jim is arrested as suspect of being Mira's mole, but he's soon released after hearing Taylor's story about his own son Lucas's part in the ignoble true motives for founding the colony.
