I made an edit to my initial post to have her just move over to Rat so he can grab one of her shortswords instead of trying to toss it.  I wasn't sure if tossing it would be okay, but moving over and letting him take it from a consenting ally with object interaction should work.  Failing that, she can hand it over, or whatever else works.<br/><br/>For those new to 5e, you can do something like open a door, draw a weapon, stuff like that and it doesn't cost you an action or movement.
