From the knowledge I've gathered about online behavior, I'm going to have to make a guess (and as strange as this may sound) that this was because the Samus player was using a girl character, and the TL was being a "gentlemen" and letting him/her get away with it (as people tend to associate the character you choose with the gender you are), feeling no form of vengeance as would any other player, possibly being one of those couple type characters you'll meet once in a while, wanting the "partner's" affirmation or whatever in return. (Either that, or he could've feared the Samus and naturally took to trying to appease him/her, even if that ment starting a fight with another player; I've seen this happen a lot before, too.)
Even though I'm going to assume you were playing as a girl character as well (Zelda), usually when there's two or more girl characters, depending on the players, it actually tends to strike up these little "bonds" even more so, where one player will hook up with another, wanting the partner's trust in return. They're actually sometimes geared toward making the other player/players (usually with a male and a female against another female) jealous and encouraging a fight. Though it doesn't sound like that's the exact case here, as the Samus attacked the TL that could've been making consolation first, but yeah, the TL didn't seem to care, as you said, so I could only assume it was probably a couple pact that just he was trying to form (or like I said before, he was just fearful). I hate those, though, and everything that's to do with them.
*cough* TL;DR more, CK.
