"Good, good.", he says, stretching up to pat your head.

"It's so much nicer that you can talk this time!"

"Last time it took a lot more to understand what he wanted.", he confides to the others.

He takes the pats on his head without resistance.

"Well, before I was mostly unconscious."

He does check with the others gathered to see how they are taking his appearance, looking for recognition on their faces.

Insight: 13

"Well, I meant last time, but yes, you were. Glad to see you up and about. Oh! I found some of your favorite!"

He proudly pulls out a handful of grubs and hands them to you.

There isn't a flicker of recognition in the faces of any of the others, mostly because they don't recognize you.

He looks at the handful of grubs and sighs before taking them and quickly swallowing them all, having learned not to chew them. He takes a deep breath and then makes the mmm noise and scooping up more water to wash them further down.

"Thank you. Father."

Clearing his throat he asks,

"What makes you think these are my friends? Do they think they are my friends?"

He asks to both father and the newcomers.

Talon flies upstream to find the source of the water, or anything contaminating the water. He will not venture into the forest, however, and will start towards the cave if he loses the stream. Perception d20: 19

He loses the stream immediately, as its burbling from the rocks, but picks it up on the other side of the rocks around and above the cave, where it funnels down through cracks in the rock. Maybe it makes up a water source for the old guy's cave? Without landing in the forested area, he's not able to taste it upstream of the cave, however.

 The grubs are filling, and as long as you swallow them quickly, the wriggling isn't too terrible.

"Well, they got here around the same time as you got back, and you were all kind of dressed the same."

"Father, where did I go? I can't seem to remember...and what is my name?"

"I don't want to talk about it.", he says, his face contorting before a smile pops back out from his beard.

"Who's hungry? I can get a pot of stew going!" 

He busies himself in his 'kitchen' getting a fire going and a kettle of water heating as he scrubs the clams and mussels he found, humming to himself as he works.

Not sure how long the others spend in the cave, but if there's time, Talon would try to find edible seeds, fruit or bugs at the edge of the forest, going up to 30ft inside. He would not eat them while alone, only collect samples of what he thinks is edible.

Nature/Survival d20: 5

Sure, you spend some time scavenging for edibles.

Does Big'Un recognize the 'son'? what does his clothes look like?

perception(with mod): 19

You don't recognize him, but he seems to be a red dragonborn. Right now he's wearing underclothes and bandages, so... Not a lot of info there.

None of the bandages seem blood soaked or dirty, at least.

'Son' notices that the is being examined and examines the newcomers right back. Maybe something on them will give him a clue as to who they are and, if he is lucky, who he is.

Perception:7

((Does 'Son' have a medallion on him like the others or just bandages and a pair of boxers?))

Just bandages and boxers, but you notice that their group color scheme matches the way too big robe that "Father" has loosely draped across his bony shoulders. It looks a lot newer than his other clothing... maybe you were wearing it when he found you?

Blue shakes his head in confusion.  He'll also check the water for any contaminants: 6

Big'Un also notices the 'off' tast of the water can he tell what it might be?

survival(with mod): 6

nature(no mod): 11

Water tastes perfectly good to both Blue and Big Un. Cool, wet and refreshing.

Son clears his throat and asks,

"So. Well." He looks over at father and continues, "You wouldn't happen to know how I ended up here would you? Or where here is? Father has been...vague."

He notes their weapons and armor and wonders if he perhaps had some of that too?

Some kind of roll that fits with pondering:16

And memory die:1

Mark will look back and forth between Fake-Mark and Son, especially paying attention to the fit of the clothes.

Investigation: 11 

Turning to Son,  he replies: "We don't.  The group of us were mostly together when we awoke, and none of us remember anything about who we are, where we are, or how we got here.  We were looking for answers when we came across him."  Mark nods his head towards the old man, then returns his attention to Son.  "How long can you remember being here?"

Son has a think... if he had any gear like that, it would either have been left where he initially woke up, or brought back here.

A bit dizzy with all the confusing attempts to figure out who and what he is, he leans against the wall, not noticing he was leaning against a torch until it starts to get warm. Doesn't seem to hurt though...

((You have resistance to fire, apparently.))

Mark is pretty sure that the robe in your colors would be a better fit on Son.
