The impression I got wasn’t that Lion-O was going to sacrifice Tygra but that he thought they could still save him if they kept fighting.
As for Panthro’s arms, that did weird me out, but I think as long as he doesn’t use the stretching ability all the time it won’t be that bad.

Seems that this episode is rather divisive, as usual 
On one hand, many see Lion-O as just willing to sacrifice Tygra, and on the other many are mad at Cheetara for giving in. We don’t know exactly what would have happened if either both had surrendered or both kept fighting, but I will say that Cheetara surrendering did at least stall for time until Panthro showed up. I believe Lion-O thought that they could save Tygra is they kept fighting, and Cheetara didn’t want to risk it. If they both surrendered, they probably would have been killed faster, and if both kept fighting then Tygra would probably have been killed. So in the end, there being a disagreement is what gave them enough time to get saved. Just seems like a morally grey area to me.
Unlike some fans, I can’t be angry at either Lion-O or Cheetara for their actions. Everyone is calling Lion-O butthurt over Cheetara, but how exactly is he supposed to react? He trusted her and sincerely thought she was into him. And he’s at lest willing to act like it’s not bothering him in front of Tygra, which shows that he doesn’t want to make his brother feel guilty or start a confrontation.
Lion-O’s problem is with Cheetara, and he wants to keep it between them. He’s not really angry that he didn’t get the girl, he’s angry for feeling deceived, and it should be obvious to know how hurtful it is to discover someone you thought was close to you really isn’t. Plus, Lion-O isn’t trying to break them up or steal Cheetara, he’s just sulking and it’s something most people do. It probably won’t last longer than a few more episodes. The only thing I didn’t like Lion-O doing was taking on the lizards by himself, but he pretty much already did that at the beginning of the ep, and he didn’t know Kaynar and Addicus were there.
As for Cheetara, I was a little shocked that she surrendered so easily, but as I explained I don’t think it’s that bad. It shows that being loyal to Lion-O and the crown isn’t her top priority, and to be honest I like it that way. Cheetara has a change in character, she’s no longer simply Lion-O’s cheerleader, and I think this development is going to good for Lion-O.
