Alonso Frame

Alonso Frame was a midshipman on board the spaceship Titanic from the planet Sto. The trip aboard the Titantic was his first trip out, and he turned down the opportunity to have a drink with his fellow crew members when Captain Hardaker told them to go and have one. He noticed that a rock storm was heading toward the ship while the shields were down, meaning that the meteors would destroy the ship. He tried to raise the shields and prevent the collision, but he was shot, non-fatally, by the Captain before he could do so. The meteors then smashed into the ship, killing the captain.

Alonso helped prevent the Titanic from crashing into the Earth, by following the Doctor's orders to keep the engines running. He was then trapped in the bridge when the Heavenly Host appeared and tried to kill him; he put a deadlock seal on the door so he could not get out and no one could get in. After the defeat of Max Capricorn, the Doctor was able to control the Heavenly Host and smash his way into the deadlocked room. The Doctor was excited to hear Midshipman Frame's full name as it afforded him an opportunity to say an "allons-y Alonso", an alliteration he had wanted to use for some time. The Doctor and Alonso then worked together trying to stop the Titanic from crashing into London and Buckingham Palace. When they were back in the air, the Doctor and Mr Copper left the ship for Earth, leaving Alonso to deal with the aftermath of the Titanic disaster. (DW: Voyage of the Damned)

Some time later, Alonso entered a nightclub for various alien species and approached the bar. He was surprised when Jack Harkness addressed him by his name, leading him to believe that Harkness was psychic. However, the Doctor had just previously sent Jack a note containing Alonso's name as a hint. The two began to flirt as the Doctor departed. (DW: The End of Time)
