I think thats as good an answer as it will get, considering there are no canon references. Your answer explains it all, and concisely so.

<p>The blood acted like a charge and amped up the signal of the seal binding him in the armor and his body by the gate this is the only thing that makes since </p>

The "signal"? There is no electric current running through the seal, if that's what you're suggesting. The blood and the metal [are physically bound](http://anime.stackexchange.com/a/3865/274). It would also help if you cited some kind of background where you originated this idea from, since nothing in the series seems to suggest this.

I think the spell seal was pretty badly done by Edward. who was a noob in alchemy at the time, and as a result Al's soul was poorly tied to the armor suit. Spilling some more blood likely helped "complete" the seal in the important parts where there was not enough blood. I may be totally wrong, but that's what it looked like to me.

I can't see why that should trigger such a response. First of all, the blood on his seal belonged to Ed, and had an intent of binding Al's soul information. ... To me, Martel's blood has no such info.

I don't think that the owner of the blood matters. It's the intent of the spell and the shape of the alchemy signature that's important. Ed knew what he wanted when he cast that spell, but he wasn't skilled enough to draw a perfect seal with his finger.

It was probably a coincidence as AL had his memories taken from him due the shock of the event. Also, I cannot think of any better way the manga writer would have him bring his memories back.

I don't understand your comment. Yes, Al had his memories taken due to shock, but how does that make it a coincidence?

Where is it stated due to shock? I believe there's some confusion here with the word shock. He got his memories back because he paid a visit to the "inner door/god/truth" which was triggered by his shock with Martel's death. His meeting with truth is what returned his memories.  This is also what's stated by the wikia.

@UsamaArshad's point is that Al's memories were _taken_ by shock, not _returned_ by it. Even though I'm inclined to agree with him in this point, if he is correct, I believe the mangaka made quite a loose decision here. Still, that's only my opinion.

Doesn't anyone else think it has more to do with the fact that Martel's body was infused with a snake with the help of a philosopher's stone? Meaning, the key ingredient isn't just blood.

At second (and third) glance(s), @Mazyod's comment actually makes sense. I mean... if not for triggering the return of Al's memory, what use did Martel, a man-snake chimer had in the series? Kinda random encounter, if you watch it intently.

How did Alphonse recover his pre-gate memories?
# How did Alphonse recover his pre-gate memories?

In FMA: Brotherhood, Alphonse recover the memories he lost after going through the Gate, by having Martel's blood spattered over his own blood seal (the one that binds his soul to his armor), and is, henceworth, able to use the knowledge inherent to it, such as using alchemy without transmutation circles.

Is there a reason for which *blood should have been splattered* over his seal for him to recover his memories?

Or was it only coincidence/traumatic?

Personally, I think it's just the blood splatter itself that "jogged his memory" so to speak in a similar way as to how the blood splattered from the transmuted body Al's soul failed to latch onto.
