Ships and Stings and Wedding Rings

Summary

''It’s Christmas again at St Mary's and time for Max’s obligatory illegal jump. On this occasion, however, they’re right up against it. A loaded gun has been left behind in Ancient Egypt and it’s up to St Mary’s historians to retrieve it before someone accidentally  blows their own head off, thus affecting the timeline for centuries to come. And as if that’s not enough, Max has inadvertently poisoned Mr Markham. It’s hot, they’re running out of supplies, they can’t find the gun, and it’s all going horribly wrong. Again.''

Spoiler Plot Summary for Ships and Stings and Wedding Rings (SSWR)
 * Elspeth Grey returns from a jump to Egypt to reveal that she's lost a gun, a Glock, on the jump
 * Markham, Peterson, and Max jump to Egypt to watch the Grey team and trading Max's wedding ring for the gun while Markham gets progressively sicker
 * Since it's obvious that Elspeth Grey can no longer be a historian, Ian Guthrie makes plans to leave; he loosely quotes Dorothy "I think I'll miss you most of all, Scarecrow" and a new nickname for Max is borne.
