how did mr.d save Percy's life through and iris message again? یا am i just imaging that??

when the manticore chased Thalia,Percy,and...Grover(i think?)behind a stand,Percy sent an Iris meassage to mr.d without the manticore knowing (he hadn't caught up yet) and had to beg mr.d to help him. Mr.D used his magical انگور vine powers and inclosed the manticore inside انگور vines...and the manticore died. Hope i helped.
