You ignore the buck for now and let him sniff and nudge all he wants. If he's so inclined to smell your fur, it hardly bothers you. Suddenly you hear him speak, in the deer language that you both understand:"Kind of odd to see each other again in this shape. After you transformed, I've hardly gotten the chance to speak to you." Your muzzle turns to utter shock. "W-what...you mean YOU'RE behind this whole mess?" "Oh, nonono, definitely not. I'm just a victim like you. We know each other though, I was your best friend in high school...my human name has kinda slipped from me after all that time, but you know what I mean." "Um, yes", you say with skepticism, "you can say that, but how do I know it's really you?" "Remember that I always had a scar on my thigh? It's shifted a bit in this form, but it's still visible..." He turns his huge body around, showing a very recognizable scar line beneath his fur, between his thigh and butt flesh. You are amazed. "But...how can you be like this? I mean, I've never seen you in this park before..." A grin seems to appear on his mouth. "I came here once, when I went on a walk by chance, and made the same mistake as you. Logically, you never saw me again after that as you wouldn't have recognized me as a buck. Been here for a few years now, I think...seemed no way out, but maybe with your help we might just be able to do it. Nice job on becoming a doe on your first day, by the way. I'm sure you'll be a fine mother of many fawns, should we fail to get out of here." "What do you mean, "mother"? I'm not--". Then suddenly a cramp in your lower abdomen hits you, but you recover within a few moments. The buck smiles triumphantly. "Yes you are. Soon, anyway. Now, what do you suggest we do?"
