Much Ado About Boimler

Boimler volunteers to test Rutherford's new transporter upgrade, which malfunctions and leaves him "phasing" between states of materialization. Tendi genetically engineers a dog with an array of freakish abilities. Boimler and the dog are sent to "The Farm", a Starfleet medical base for unusual conditions, on the USS Osler. Freeman is assigned to a covert mission and Mariner's old friend Captain Amina Ramsey takes temporary command. To avoid being promoted by Ramsey, Mariner displays uncharacteristic incompetence but is forced to confidently take control when the Cerritos finds the USS Rubidoux being torn apart by a hatching space-born entity. Other patients on the Osler fear the Farm is a horrible place and stage a mutiny. Boimler recovers from the phasing and attempts to make peace.
