ever_lovin | Gifts Ben has left with Bar

Jennifer Walters: A nice fountain pen she will recognize as being a functioning prop from Perry Mason, a pair of titanium handcuffs and a note which reads, "Sorry I couldn't afford admantium."

Penny: A flawless seeming crystal and a note which reads, "I hope all's been good with you. I haven't seen you around but you are in my thoughts. This is a Shi'ar Singing Crystal. It takes musical notes and sounds (like the sounds you make) and does neat things with them. Have fun playing with it."

Kate Bishop: A single arrow in a box and a note which reads, "I got this from Artemis way back in the day. It's just been sitting in this box ever since. Maybe you have a better use for it?"

Billy Kaplan: A nickel and enamel reproduction of Captain America's shield, about the size of a half dollar coin, and a note which reads, "Never forget why you fight or fought."

Teddy Altman: An old watch with a leather wrist band. Engraved on the back of the watch is the name Dr. Walter Lawson. The note with this reads, "Every son should own something that was his fathers. When Mar-Vell first came to Earth he used this alliance, wasn't sure if you knew that."

So maybe Ben bent the "No Using the Time Platform for Frivolous Reasons" rule.
