So like the titles says can a TK'r tk a friendly character carrying a object?
Ex. Magneto uses telekinesis on Colossus who is carrying a object.

Absolutely, it's strange that you can't tk an ultra heavy but you can tk someone carrying one

It's like how cartoons can walk off cliffs without gravity affecting them until they look down and notice the cliff is there. Just focus on the character and not the object and it's fine.

Yes you can. End of line.
